Part Number: BQ25792


Tool/software:

Hi team,

My customer want to select a charger device.

The parameter is:

Input voltage: 12V

Cell Counts: 3

Charge current: 3A

Charge terminate voltage: 12.4V

I promoted BQ25792 and the schematic is shown as below. It looks fine for me. Could you help review it again, thanks!

    HI Jayden,

    ACDRVx = GND if not used.

    SDRV tied to GND through 1000pF if not used.

    PROG pin resistor is not set for 3S.

    TS pin resistors are not correct for 10kohm thermistor.

    Also, can you find out what the opto-coupler is for?

    Regards,

    Jeff
