USB Controller USB 2.0 I2C Interface 24-QFN (4x4) The STUSB4500QTR is a standalone USB Type-C Power Delivery (PD) controller from STMicroelectronics designed for power sink applications (devices that receive power, like chargers, IoT devices, or battery-powered systems). It enables automatic negotiation of USB Power Delivery contracts (up to 100 W: 20 V / 5 A) without requiring an external microcontroller, thanks to its built-in auto-run algorithm. Power profiles (PDOs) can be pre-configured and stored in internal non-volatile memory, simplifying system design and reducing component count. The device is optimized for modern USB-C designs, offering robust protection, high-voltage tolerance, and support for operation even from a dead battery state. Key Features Power Delivery & Control Standalone USB Type-C™ and USB PD sink controller Supports up to 100 W (20 V, 5 A) power negotiation Auto-run mode (no MCU required) for PD negotiation Up to 3 configurable sink PDO profiles stored in NVM Power Management Dead battery mode support (can start with no battery power) Dual power supply inputs: V_SYS: 3.0 V – 5.5 V V_DD: 4.1 V – 22 V Integrated VBUS monitoring and control Integrated Functions Built-in VBUS switch gate drivers (PMOS) Internal/external VBUS discharge paths I²C interface for configuration and monitoring Protection & Reliability Short-to-VBUS protection on CC pins (up to 22 V) High-voltage tolerance: Up to 28 V on VBUS pins ESD protection: 3 kV HBM / 1.5 kV CDM Physical & Environmental Package: QFN-24 (4×4 mm) Operating temperature: –40°C to +105°C Industrial-grade reliability Compliance & Compatibility Certified for: USB Type-C Rev 1.2 USB PD Rev 2.0 Interoperable with USB PD 3.0 #commonpartslibrary #integratedcircuit #usbcontroller

1/1 Transceiver Half RS422, RS485 8-SOIC These devices have robust 3.3-V drivers and receivers in a small package for demanding industrial applications. The bus pins are robust to ESD events with high levels of protection to Human-Body Model and IEC Contact Discharge specifications. Each of these devices combines a differential driver and a differential receiver which operate from a single 3.3-V power supply. The driver differential outputs and the receiver differential inputs are connected internally to form a bus port suitable for half-duplex (two-wire bus) communication. These devices feature a wide common-mode voltage range making the devices suitable for multi-point applications over long cable runs. These devices are characterized from –40°C to 125°C 1• Small-size VSSOP Packages Save Board Space, or SOIC for Drop-in Compatibility • Bus I/O Protection – >±15 kV HBM Protection – >±12 kV IEC 61000-4-2 Contact Discharge – >±4 kV IEC 61000-4-4 Fast Transient Burst • Extended Industrial Temperature Range –40°C to 125°C • Large Receiver Hysteresis (80 mV) for Noise Rejection • Low Unit-Loading Allows Over 200 Connected Nodes • Low Power Consumption – Low Standby Supply Current: < 2 µA – ICC < 1 mA Quiescent During Operation • 5-V Tolerant Logic Inputs Compatible With 3.3-V or 5-V Controllers • Signaling Rate Options Optimized for: 250 kbps, 20 Mbps, 50 Mbps • Glitch Free Power-Up and Power-Down Bus Inputs and Outputs 2 Applications • Factory Automation • Telecommunications Infrastructure • Motion Control #SN65HVD75D #RS485 #RS422 #Transceiver #TexasInstruments #IndustrialCommunication #FactoryAutomation #MotionControl #TelecomInfrastructure #ESDProtection #HalfDuplex #InterfaceIC #EmbeddedSystems #IndustrialElectronics #DataCommunication
