BQ76200: Maximum sink current of DSG pin of BQ76200

Part Number: BQ76200

1.My design does not have D1 and Rs. Rdsg is 0 ohms. The SLUA794 document mentions that this design may damage the BQ76200. Is there a high probability of damage? Maximum sink current of DSG pin?

    Hi Rambor,

    The need for D1 and Rs and a non-zero RDSG depends on the voltages and transient behavior of your system. Your system may work okay with these settings. We do not know at what sink current DSG could be damaged, but some lab testing showed that using a higher resistor value for RDSG (like 100 ohms) prevents damage when large transients are present.

    If the voltage of your PACK voltage is not very high, then RDSG of 0 ohms might be fine.

    Best regards,

    Matt
