1.5A USB-Friendly Li-Ion Battery Charger and Power-Path Management IC with 4.2 VBAT The BQ24075TRGTR (from Texas Instruments) is a highly integrated single-cell Li-Ion / Li-Polymer linear battery charger IC with power-path management. It is designed for portable and space-constrained applications, allowing a device to be powered from a USB port or AC adapter while simultaneously charging the battery. The device integrates charging control, power-path management, and safety features into a compact package. A key feature is its Dynamic Power Path Management (DPPM), which ensures the system is powered even when the battery is low or absent, while intelligently managing charging current. Key Features Battery Charging Supports single-cell Li-Ion / Li-Polymer batteries Up to 1.5 A programmable charge current Three-phase charging: Pre-charge (conditioning) Constant current Constant voltage Fixed 4.2 V charge voltage Power Path Management Dynamic Power Path Management (DPPM): Powers system and charges battery simultaneously Prioritizes system load over charging Allows system operation even with: Deeply discharged battery No battery connected Input & Power Features Operates from: USB input (100 mA / 500 mA selectable) AC adapter Programmable input current limit up to 1.5 A Input voltage range: ~4.35 V to 6.4 V (28 V max rating) Input dynamic power management (VIN-DPM) prevents source overload Protection & Safety Thermal regulation and shutdown Over-voltage protection (OVP) Short-circuit and reverse current protection Battery temperature monitoring (NTC thermistor input) Battery disconnect (SYSOFF) feature Control & Status Standalone operation (no MCU required, resistor-programmable) Charge status outputs: Charging Charge complete Power good Physical Characteristics Package: 16-pin VQFN (3 mm × 3 mm) Operating temperature: –40°C to +85°C #commonpartslibrary #integratedcircuit #powermanagement #batterycharger
