A typical application consists of the device configured as a standalone battery charger for Lithium-Ion, Li-Polymer, LiFePO4, or NiMH batteries. The battery charge profile and the safety charge timer are configured using a pulldown resistor on the CHM_TMR pin. The charge voltage and the number of cells are configured using a pulldown resistor on the VSET pin. Charge current is configured using a pulldown resistor on the ISET pin. A battery thermistor may be connected to the TS pin to allow the device to monitor battery temperature and control charging. Pulling the CE pin high disables the charging function. Charger status is reported via the STAT1 and STAT2 status pins.
