the bq25186 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 1a charging and system loads of up to 3.125a.
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 3v minimum input voltage operation and can withstand 25v absolute maximum line transients. the device integrates a single push-button input to reduce the total solution footprint.
