Description

The BQ21061 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, a LDO, and push-button controller.

The BQ21061 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 ICs and system loads for optimal system operation.
