Texas Instruments Battery Charge Management

Texas Instruments’ BQ25150 battery charge management IC is optimized for wearable devices, integrating a charger, LDO, ADC, and push-button controller in a small package. 

The linear charger can supply up to 500mA and has a termination current as low as 0.5mA for fast and accurate charging. The I2C programmable LDO can output from 0.6V to 3.7V at up to 150mA, and also configured as a load switch. 

The ADC can monitor charge current, the battery thermistor, voltages, or an external input. The push-button controller can be used for device wakeup and reset and has adjustable timers, eliminating the need for a separate controller. 

The BQ25150 has ultra-low quiescent current for maximum battery life and is optimized for a 5V USB input. It uses a 2mm x 1.6mm CSP package with a 12mm2 total solution size.
