bq25123 Battery Charge Management Solution

Texas Instruments bq25123 Battery Charge Management Solution is a highly integrated battery charge management IC that integrates the most common functions for wearable devices. These functions include a linear charger, regulated output, load switch, manual reset with timer, and battery voltage monitor. The integrated buck converter is a high efficiency, low I_Q switcher using DCS-Control™ that 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.
