Could you tell me how to connect the FUSE terminals when using two BQ76952s?

    Hi Kentaro,

    If the FUSE pins are not used, they can be left floating or they can be connected to a resistor to the VSS pin of each IC. If these pins need to control a fuse on the board, the BQ76952EVM shows how a fuse can be controlled with multiple stacked devices - there are 4 BQ7718 devices that are stacked to control one fuse. This same circuit idea can be used for the stacked BQ76952 FUSE pins.

    Best regards,

    Matt
