TPS65987D: Hard Reset - Bypass option?

Part Number: TPS65987D

Hello,

Hard reset will initiate power negotiation in USB PD.

1. Would it cause brownout if used in battery-less solution.

2. Could HR be bypass in the firmware? What would be the risks?

Thanks,

kay

    Hi Kay,


    There should not be a Hard Reset during a successful PD negotiation. A Hard Reset would occur under an error condition. When a Hard Reset does occur, there will be a disconnect on the Type-C Port. If the device is bus-powered, then it would temporarily lose VBUS until a renegotiation occurs.

    Thank you,
    Eric
