Charger IC Lithium Ion 16-VQFN (3x3) The BQ24075RGTR is a standalone linear charger and power-path management integrated circuit developed by Texas Instruments for single-cell lithium-ion and lithium-polymer battery applications. The device is designed for portable and space-constrained electronic systems requiring efficient battery charging, USB compatibility, and simultaneous system power delivery. The integrated dynamic power-path management architecture enables the system load to be powered while independently charging the battery. The charger supports operation from either a USB power source or an external adapter and includes programmable charging and input current limiting functions for optimized power management. The device incorporates multiple protection and monitoring features including thermal regulation, overvoltage protection, reverse current protection, battery temperature monitoring, and safety timers. The BQ24075RGTR also provides battery disconnect capability through the SYSOFF control function, making it suitable for low-power and portable embedded designs. Typical applications include portable consumer electronics, handheld instruments, wearable devices, wireless accessories, battery-powered IoT equipment, medical portable systems, and embedded rechargeable products. Device Features Standalone single-cell lithium-ion and lithium-polymer battery charger Integrated power-path management architecture Simultaneous battery charging and system power support USB-compatible input current limiting Programmable fast-charge current capability Dynamic power management for unstable or limited input sources Battery temperature monitoring through external thermistor input Integrated thermal regulation and protection mechanisms Reverse current, short-circuit, and input overvoltage protection Programmable safety timers for pre-charge and fast-charge modes Charging status and power-good indication outputs Battery disconnect functionality through SYSOFF control Compact surface-mount VQFN package implementation Electrical Characteristics Designed for single-cell lithium-ion or lithium-polymer batteries Fixed battery regulation voltage suitable for standard single-cell charging Supports USB and external adapter input operation Linear charging topology Wide operating temperature range for portable and industrial applications Programmable input current limit for USB compliance and adapter compatibility Package Information Package Type: VQFN Pin Configuration: Sixteen-pin package Mounting Style: Surface mount Package Dimensions: Compact three-millimeter square footprint Functional Overview The BQ24075RGTR manages power distribution between the external input source, the system load, and the rechargeable battery. When external power is present, the device prioritizes powering the system while charging the battery according to programmable charging parameters. Dynamic power management prevents excessive loading of weak USB or adapter sources by automatically reducing charging current when necessary. Thermal regulation circuitry continuously monitors device temperature and adjusts charging operation to maintain safe operating conditions. Additional integrated protection functions ensure reliable operation during fault conditions such as input overvoltage, battery temperature abnormalities, reverse current flow, and output short circuits. #commonpartslibrary #integratedcircuit #powermanagement

Charger IC Lithium Ion 49-WLP (3.46x3.46) The MAX77962 is a high-performance wide-input 3.2A buck-boost charger with a Smart Power Selector™ and operates as a reverse buck without an additional inductor, allowing the IC to power USB On-the-Go (OTG) accessories. The device integrates low-loss power switches, and provides small solution size, high efficiency, low heat, and fast battery charging. The reverse buck has true-load disconnect and is protected by an adjustable output current limit. The device is highly flexible and programmable through I2C configuration or autonomously through resistor configuration. The battery charger includes a Smart Power Selector to accommodate a wide range of battery sizes and system loads. The Smart Power Selector allows the system to start up gracefully when an input source is available even when the battery is deeply discharged (dead battery) or missing. For battery safety/authentication reasons, the IC can be configured to keep charging disabled, and allow the DC-DC to switch and regulate the SYS voltage. The system processor can later enable charging using the appropriate I2C commands. Alternatively, the IC can be configured to automatically start charging. ● 3.5V to 23V Input Operating Range, 30VDC Withstand Voltage ● 97% Peak Efficiency at 9VIN/7.4VOUT/1.5AOUT ● Reverse Leakage Protection ● 50mA to 3.15A Programmable Input Current Limit ● 50mA to 3.2A Programmable Constant Current Charge ● Remote Differential Voltage Sensing ● 600kHz or 1.2MHz Switching Frequency Options ● System Instant On with Smart Power Selector PowerPath ● Charge Safety Timer ● Die Temperature Regulation with Thermal Foldback Loop ● Input Power Management with Adaptive Input Current Limit (AICL) and Input Voltage Regulation ● 10mΩ BATT to SYS Switch, Up to 10A Overcurrent Threshold ● Reverse Buck Mode 5.1V/1.5A to Support USB OTG ● JEITA Compliant with NTC Thermistor Monitor ● I 2C or Resistor Programmable ● 3.458mm x 3.458mm 49-Bump WLP #CommonPartsLibrary #IntegratedCircuit #PowerManagement #MAX77962
