Texas Instruments bq25155EVM Evaluation Module
Texas Instruments bq25155EVM Evaluation Module is an integrated battery charge management IC that integrates the most common functions for wearable devices. These include a linear charger, regulated output, load switch, manual reset with timer, ADC, ship mode, and advanced power path.
The Texas Instruments bq25155EVM Evaluation Module offers a low quiescent current during operation, and shutdown enables maximum battery life. The device supports charge currents from 1.25mA to 500mA. Parameters such as input current limit, charge current, regulated PMID output, and LDO output voltage are programmable through the I2C interface. The Evaluation Module also features a multi-point ADC to measure different parameters on the charger, including an optional ADC input. A standard li-ion charge profile charges the battery with three phases: precharge, constant current, and constant voltage.
Features
- Configurable battery charger
- Multi-point ADC to measure seven channels
- Advanced power path to power system through either battery or adapter
- Programmable hard and soft reset
- 0.5% accurate battery voltage regulation
- Wake timers for push button
