Mini linear single-cell Li-ion charger with full protections, low leakage, tiny package for wearables and small IoT devices.
The BQ25101YFPR is a compact, fully integrated linear charger designed for single-cell Li-ion and Li-polymer batteries. Featuring low leakage and a tiny package, it's ideal for wearables and small IoT devices.
Integrated Charging Solution: Complete linear charger with internal power FET, supporting trickle precharge, constant-current charging, and constant-voltage termination.
Configurable Charging: Charge current is easily set via an external resistor for design flexibility.
Comprehensive Protection: Integrated thermal regulation, input reverse protection, overvoltage protection, short-circuit protection, and battery temperature sensing.
Efficient Operation: Open-drain pin reports charge status, while ship mode drastically reduces battery leakage when input power is removed.
Space-Saving Design: Tiny WLCSP package minimizes PCB space requirements.
