Product details

Battery monitor with I²C control for 1–4 cell packs

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.

Frequently asked questions

Does BQ25703ARSNR support I²C battery charging?

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.

Is BQ25703ARSNR compatible with 4-cell Li-ion?

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.
