The power-path feature allows the Supports 5-V USB 2.0/3.0 and 12-V USB Power bq24260/1/1M/2 to power the system from a high Delivery (bq24261/1M) efficiency DC-DC converter while simultaneously and • Small Solution Size In a 2.4-mm × 2.4-mm 36-Pin independently charging the battery. The power path WCSP or 4-mm × 4-mm 24-Pin QFN Package also permits the battery to supplement the system current requirements when the adapter cannot. Many – Total Charging Solution Can be 50 mm2 or features are programmable using the I2C interface. Less With WCSP To support USB OTG applications, the • Safe and Accurate Battery-Management bq24260/1/1M/2 is configurable to boost the battery Functions Programmed Using I2C Interface voltage to 5 V and supply up to 1 A at the input. The – Charge Voltage, Current, Termination battery is charged with three phases: precharge, Threshold, Input Current Limit, VIN_DPM constant current, and constant voltage. Thermal regulation prevents the die temperature from Threshold exceeding 125°C. Additionally, a JEITA-compatible – Voltage-Based, JEITA-Compatible NTC battery pack thermistor monitoring input (TS) is Monitoring Input included to prevent the battery from charging outside – Thermal Regulation Protection for Input of its safe temperature range.
