The BQ25190 is a highly integrated battery management unit that integrates the most commonly used functions for wearable devices: a linear charger with power path, one step-down switching converter (Buck), one buck-boost switching converter (Buck-boost), two LDOs (LDO1 and LDO2), manual reset with timer (MR) , multi-channel analog-to-digital converter (ADC), as well as four multifunctional general-purpose input/outputs (GPIO).

The integrated charger supports charge current from 5mA to 1A that enables quick and accurate charging while providing a regulated voltage to the system. The regulated system voltage (VSYS) can be configured through I2C based on the recommended operating conditions of the downstream system loads. Other operation parameters such as the input current limit, charge current, Buck converters’ output voltages, Buck-boost converters’ output voltage, and LDOs’ output voltages are also programmable through the I2C interface.

The BQ25190 features low quiescent current during operation and shutdown, which enables longer battery life.
