Description
General part information
BQ25185 Series
The BQ25185 is a linear battery charger IC focusing on small solution size and low quiescent current for extending battery life. The device is available in a leadless, small package with a thermal pad giving thermal performance. The device can support up to 1-A charging and system loads of up to 3.125 A.
The battery is charged using a standard Li-ion or LiFePO4 charge profile with three phases: precharge, constant current and constant voltage. Thermal regulation provides the maximum charge current while managing the device temperature. The charger is also optimized for battery to battery charging with 3-V minimum input voltage operation and can withstand 25-V absolute maximum line transients. The device integrates a single push-button input to reduce the total solution footprint.
