bq25120 Integrated Battery Charge Management IC

Texas Instruments bq25120 Integrated Battery Charge Management IC integrates the most common functions for wearable devices and IoT. These functions include linear charger, regulated output, load switch, manual reset with timer, and battery voltage monitor. The integrated buck converter is a high efficiency, low IQ switcher using DCS control. This extends light load efficiency down to 10µA load currents. The low quiescent current during operation and shutdown enables maximum battery life. The device supports charge currents from 5mA to 300mA. The input current limit, charge current, buck converter output voltage, LDO output voltage, and other parameters are programmable through the I2C interface.
