The Texas Instruments BQ25703ARSNR is a multi-chemistry battery monitor that communicates over an I²C interface, supporting 1 to 4 series cells. It integrates over-current, over-temperature, and over-voltage fault protection, making it a fit for portable electronics, power tools, and industrial battery-backed systems where the host needs to read charge state and set thresholds over a serial bus.
Yes, the BQ25703ARSNR uses an I²C interface for communication with the host controller, allowing the system to monitor battery parameters and configure protection thresholds over the bus.
Yes, the BQ25703ARSNR supports 1 to 4 series cells, so a 4-cell Li-ion pack (nominal 14.8 V) is within its operating range.
