All details fully confirmed from Azoteq's official IQS7222B datasheet and multiple verified distributor sources. Here's the complete spec. Engineering Specification — IQS7222B102QNR Manufacturer: Azoteq (Pty) Ltd Device Family: IQ Switch® ProxFusion® Series — IQS7222B General Description The IQS7222B102QNR is a high-channel-count capacitive touch and proximity sensing controller integrated circuit manufactured by Azoteq, belonging to the ProxFusion series of intelligent human interface sensing devices. The IQS7222B is a sensor fusion device for various multi-button applications that is fully I²C compatible, with on-chip calculations that enable the IC to respond effectively even in the lowest-power modes. It represents an expanded-channel evolution within Azoteq's IQS7222 family, offering a substantially higher mutual capacitance channel count than the IQS7222A variant while maintaining the same ProxFusion design philosophy of combining sophisticated on-chip sensing intelligence with a minimal external component requirement and a compact surface-mount package. Molex The IQS7222B is a highly flexible ProxFusion device that can configure up to eighteen mutual capacitance buttons or up to eight self-capacitance buttons, with nine external sensor pad connections available in the QFN package variant. Alternatively, it can configure up to twenty mutual capacitance buttons or eighteen mutual capacitance buttons with a proximity wake-up function. This high degree of channel configurability makes the device adaptable to a very broad range of physical interface configurations, from simple multi-button panels to complex touch arrays with simultaneous proximity wake-up capability, all within a single fixed-footprint IC that does not require a change of device between product variants with different button counts. MolexAmazon Target applications for the IQS7222B include remote control user interfaces, home automation device user interfaces, and wireless speaker controls. These application domains share common requirements for robust touch detection through cosmetic overlay materials such as glass, plastic, or painted surfaces, reliable operation in environments where the device may be exposed to moisture or contamination, and power efficiency sufficient to support battery-powered or always-on operation without significantly impacting battery life. The device's on-chip power management architecture, which features automated system power modes for optimal response versus consumption, directly addresses these requirements by allowing the device to spend the majority of its time in a low-current sleep or ultra-low-power state while still waking promptly in response to proximity or touch events. MolexMolex Built-in basic functions include automatic tuning, noise filtering, debounce and hysteresis, and dual direction trigger indication. The automatic tuning capability, implemented through Azoteq's proprietary ATI algorithm, compensates for variations in electrode capacitance that arise from PCB manufacturing tolerances, overlay thickness variation, and environmental factors such as temperature and supply voltage drift. This self-calibration eliminates the need for individual unit factory calibration and ensures consistent touch sensitivity across the full production run of any product built around this device. The noise filtering and debounce functions further improve the reliability of touch event detection in electrically noisy environments, preventing false triggers from electrical interference or mechanical vibration that could otherwise cause spurious button events in poorly filtered designs. Molex Both mutual capacitance and self-capacitance designs are possible with the IQS7222B, giving system designers the flexibility to choose the sensing modality most appropriate for their electrode layout and overlay configuration. Mutual capacitance sensing offers better noise immunity and the ability to detect touch through thicker overlay materials, while self-capacitance sensing allows a simpler single-electrode layout per button with potentially higher raw sensitivity. The I²C communication interface supports IRQ/RDY signaling at speeds up to Fast-Plus mode, providing efficient, low-latency event notification to the host microcontroller without requiring continuous polling of the device. The "QNR" suffix in the part number designates the QFN twenty-pin package variant, which offers the maximum external pad count for mutual capacitance configurations.

Capacitive Touch Buttons, Slider, Wheel 18-WLCSP (1.62x1.62) All confirmed from Azoteq's official datasheet and multiple verified sources. Here's the complete spec. Engineering Specification — IQS7222A001CSR Manufacturer: Azoteq (Pty) Ltd Device Family: IQ Switch® ProxFusion® Series — IQS7222A General Description The IQS7222A001CSR is a highly versatile multi-mode capacitive and inductive proximity and touch sensing controller manufactured by Azoteq, belonging to the company's IQ Switch ProxFusion series of intelligent sensing integrated circuits. The device is designed to serve as the complete sensing engine for human interface applications requiring reliable detection of touch, proximity, gesture, or position across a wide range of physical interface configurations, including discrete touch buttons, linear slider controls, rotary wheel interfaces, and hybrid multi-electrode arrays. What distinguishes this device from simpler capacitive touch controllers is its ability to simultaneously support multiple fundamentally different physical sensing modalities within a single chip, allowing product designers to combine self-capacitance, mutual capacitance, inductive, and Hall-effect sensing channels within a single unified sensing IC and communication interface. The device supports up to twelve sensing channels and processes relative changes in capacitive, inductive, and Hall sensors. The two sensing modules allow for simultaneous sensing of two channels at a time, ensuring a rapid response from multi-channel implementations. Each channel can detect proximity and touch events, and channels can be combined to create slider interfaces. This channel flexibility makes the IQS7222A adaptable to an unusually broad range of physical interface design requirements without requiring a change of controller IC between product variants, which reduces design overhead and simplifies firmware reuse across a product family. Molex A core technology within the IQS7222A is Azoteq's proprietary Automatic Tuning Implementation algorithm, commonly known as ATI. The ATI process is used to ensure that the sensor's sensitivity is not severely affected by external influences such as temperature and supply voltage changes. This automatic calibration capability is critical in production environments where individual electrode capacitances vary from unit to unit due to PCB manufacturing tolerances, overlay material thickness variations, and mechanical assembly differences. Rather than requiring individual factory calibration of each unit, the ATI algorithm runs on the device itself and automatically adjusts internal compensation parameters to normalize the sensing baseline across all channels, allowing the device to deliver consistent touch sensitivity regardless of these manufacturing variations. Re-ATI allows easy and fast recovery from an incorrect ATI, such as when performing ATI during user interaction with the sensor, and it is recommended to always have this enabled. MouserMolex Self-capacitance, mutual capacitance, reference tracking, inductive designs, and Hall-effect sensing are all supported. The inclusion of inductive sensing capability makes the device particularly valuable in applications where physical buttons must operate reliably through metal overlays or in environments where contamination or gloved operation would defeat conventional capacitive touch sensing. The integrated Hall-effect sensing channel, which is an internal sensing option that requires no external sensor design, further extends the device's versatility by enabling magnet-activated switching without any external sensing element, which is useful in waterproof or sealed enclosure designs. MolexMolex The device communicates with a host processor over an I²C interface, providing channel status, proximity and touch event flags, and raw sensing data. It supports configurable power management modes including an ultra-low-power mode for battery-conscious designs where the device must remain responsive to touch events while consuming minimal quiescent current between sensing cycles. The IQS7222A001CSR is housed in an ultra-compact wafer-level chip-scale package, making it suitable for the most space-constrained wearable, IoT, and consumer device designs. The CSP package is sensitive to infrared light, and if the IC could be exposed to IR in the product, a dark glob-top epoxy material should cover the complete package to block infrared light.

2A 150KHz 40V Buck DC to DC Converter The XL1509-5.0E1 is a fixed frequency PWM buck step-down DC-DC converter capable of driving a load with high efficiency, low ripple, and excellent line and load regulation. It is manufactured by XLSEMI and belongs to the XL1509 product family, a series of fixed-output and adjustable-output step-down switching regulator ICs designed to simplify the design of compact, efficient DC power conversion stages in a wide range of embedded, industrial, and consumer electronics applications. The "5.0" designation in the part number specifies that this variant produces a fixed regulated output voltage of five volts, making it directly suited to powering five-volt logic, microcontrollers, sensors, communication modules, and other standard digital subsystems from higher-voltage DC rails without requiring a linear regulator and its inherent power dissipation penalty. Unikeyic Electronics The XL1509 requires a minimum number of external components, making it simple to use, and includes internal frequency compensation and a fixed-frequency oscillator. The PWM control circuit is able to adjust the duty ratio linearly from zero to one hundred percent. This internal compensation architecture removes the burden of control loop design from the system engineer, which is a common point of complexity in discrete buck converter designs, and allows the device to be implemented with a straightforward application circuit consisting of an input capacitor, an output inductor, a freewheeling Schottky diode, and an output capacitor, without requiring additional feedback network components in the fixed-output version. Unikeyic Electronics The device operates across a wide input voltage range, accepting input rails ranging from just above the output voltage all the way up to the high end of the input range, making it compatible with a variety of common source voltages including twelve-volt, twenty-four-volt, and other industrial bus rails frequently encountered in embedded and industrial power system designs. This wide input range also makes it suitable for battery-powered applications where the supply voltage varies considerably across the battery discharge cycle, as the converter maintains a regulated output throughout the input voltage window. The fixed switching frequency is set internally at a value that represents a practical tradeoff between external component size and switching loss, allowing the use of standard commodity inductors and electrolytic or ceramic output capacitors without requiring unusually large or small values. An enable function and an overcurrent protection function are built inside. When a secondary current limit condition occurs, the operating frequency is reduced to a lower switching frequency, which limits the energy delivered per cycle and prevents damage to the power switch and external components during sustained overload events. This dual-level current protection approach provides both instantaneous peak current limiting and sustained overload protection, improving the robustness of designs built around the device in applications where load transients or fault conditions may cause temporary overcurrent conditions. Unikeyic Electronics The device is housed in a standard eight-pin small-outline integrated circuit surface-mount package, making it compatible with automated pick-and-place and reflow soldering assembly processes and suitable for compact power supply layouts on densely populated PCBs.
