Hot-selling and scarce BQ24261MYFFT Power-Path Management and USB-OTG Support DSBGA spot stock

Product Descriptions

The bq24260/bq24261/bq24261M/bq24262 is a highly integrated single-cell Li-Ion battery charger and system power path management device that supports operation from either a USB port or wall adapter supply. The power-path feature allows the bq24260/1/1M/2 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 I2C interface.

To support USB OTG applications, the bq24260/1/1M/2 is configurable to boost the battery voltage to 5 V and supply up to 1 A at the input. The battery is charged with three phases: precharge, constant current, and constant voltage. Therma 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.
