The bq24266 is highly integrated single cell Li-Ion battery charger and system power path management devices that supports operation from either a USB port or wall adapter supply. The power path feature allows the bq24266 to power the system from a high efficiency DC to 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. To support USB OTG applications, the bq24266 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.
