Description
General part information
BQ25155 Series
The BQ25155 is a highly integrated battery charge management IC that integrates the most common functions for wearable, portable and small medical devices, namely a charger, a regulated output voltage rail for system power, ADC for battery and system monitoring, a LDO, and push-button controller.
The BQ25155 IC integrates a linear charger with Power Path 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 I 2C based on the recommended operating condition of downstream IC’s and system loads for optimal system operation.
The device supports charge current up to 500 mA and supports termination current down to 0.5 mA for maximum charge. The battery is charged using a standard Li-Ion charge profile with three phases: pre-charge, constant current and constant voltage regulation.
