Part Information
BQ25872YFFT image
RoHS Compliant
The device is a 7-A battery switch charger with an integrated 10-bit ADC. The high-current battery switch charger is a 13-mΩ 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. The I2C serial interface of the device can operate at speeds up to 1 MHz and allows access to the ADC’s measurements of the different charging parameters and also allows for flexible software control of the device. The INT pin provides instantaneous feedback to the host in case of a fault condition. I2C status registers allow the host to read the current status of all faults and events. The device comes in a DSBGA package.
