Integrating the most common functions for wearable devices and IoT
applications, Texas Instruments' (TI) bq25120 integrated battery charge
management IC is now available from Mouser stock.
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
Typical applications include smart watches and other wearable devices,
fitness accessories, health monitoring, medical accessories and rechargeable
toys.
