bq25155 Battery Charge Management IC

Texas Instruments bq25155 Battery Charge Management IC integrates the most common functions for wearable and portable devices. These functions include a charger, a regulated output voltage rail for system power, an ADC for battery and system monitoring, an LDO, and a push-button controller. The bq25155 IC integrates a linear charger with PowerPath that enables quick and accurate charging for small batteries while providing a regulated voltage to the system. The regulated system voltage (PMID) output may be configured through I2C based on the recommended operating conditions of downstream ICs and system loads for optimal system operation.
