bq25871 Battery Switch Charger

Texas Instruments bq25871 Battery Switch Charger is a 7A battery switch charger with an integrated 10-bit ADC. The high-current battery switch charger is a 13mΩ MOSFET with reverse current blocking designed for high efficiency and minimal voltage drop. The high charge current capability of the device makes it ideal for smartphones, tablets, and other portable devices with large battery capacity. The integrated 10-bit ADC can measure input voltage and current, battery voltage and current, as well as battery temperature and input connector temperature. This allows the user application to continuously monitor the power input and battery charging parameters to ensure the safety of the battery charging. The flexible OVP and OCP thresholds for VBUS, VOUT, and battery can be modified via I²C registers as the battery goes through constant current (CC) and constant voltage (CV) mode.
