BQ24262RGET

The BQ24262RGET is a single cell switch-mode Li-ion Battery Charger that supports operation from either an USB port or wall adapter supply. The power-path feature allows the bq24262 to power the system from a high efficiency DC-DC converter while simultaneously and independently charging the battery. The power path also permits the battery to supplement the system current requirements when the adapter cannot. Many features are programmable using the I?C interface. To support USB OTG applications, the bq24262 is configurable to boost the battery voltage to 5V and supply up to 1A at the input. The battery is charged with three phases: precharge, constant current and constant voltage. Thermal regulation prevents the die temperature from exceeding 125°C. Additionally, a JEITA-compatible battery pack thermistor monitoring input (TS) is included to prevent the battery from charging outside of its safe temperature range.
