Texas Instruments bq25120AEVM/bq25122EVM Evaluation Modules (EVMs)
Texas Instruments bq25120AEVM/bq25122EVM Battery Charge Management Evaluation Modules (EVMs) for wearables and hearables which functions include a linear charger, regulated output, load switch, manual reset with timer, and battery voltage monitor. Maximum battery life is enabled through low quiescent current during operation and shutdown. Charge currents are supported from 5mA to 300mA, while other parameters are programmable through the I2C interface. These parameters include input current limit, charge current, PWM output voltage, and LDO output voltage. Three phases of the standard li-ion charge profile are precharge, constant current, and constant voltage.
Features
- Configurable 300mA buck regulator (1.8V default)
- 700nA typical Iq with PWM enabled (no load)
- Up to 300mA charge current for fast charging
- 0.5% accurate battery voltage regulation (configurable from 3.6V to 4.65V in 10mV steps)
- Configurable termination current down to 500µA
