3 Description 

The BQ25619 is a highly integrated 1.5-A switchmode battery charge management and system Power Path management device for single cell Li-Ion and Lipolymer battery. The low impedance Power Path optimizes switch-mode operation efficiency, reduces battery charging time and extends battery run time during discharging phase. The BQ25619 can charge wearable accessories in direct path from an adapter or in boost mode from a battery, with PMID_GOOD pin to control the external PMOS FET load switch.
