The uP8013B is a highly integrated complete battery charger with power-path management. The uP8013B features a smart power selector to make the best use of limited input power. Input current limit and battery charge current are independently programmable by I2C interface. System-path current limit sense can connect a resistor from ILIM to GND terminal provides a programmable current limit is set by I2C interface, while USB input current can be set to 0.1A and 0.5A. The input power can be turned off by SYSOFF pin.

The uP8013B charges battery with a minimum current about 8.5mA charge when the battery voltage is lower than 2V,and the charger works with 1/10 charge current when the battery voltage is between 2V and 2.8V . The charger works with fixed charge current when the battery voltage is between 2.8V and 4.2V, and the charger works with fixed voltage when the battery voltage is 4.2V. The voltage level could be set by an I2C interface. The uP8013B provides a programmable time-out function that initiates fault alarm if charge cycle is not complete within the time-out period. Other features include input over-voltage protection, thermal fold-back charge current, NTC thermistor interface and automatic recharge. The uP8013B is available in thermal enhanced and space-saving WLCSP2x2 – 25B package.
