DRV8876: nFAULT pin & nSLLEP pin

Kazuki Kitajima

Part Number: DRV8876

Hello team,

Could you tell me the treatment for the pins below?

1. nSLEEP: If this pin connects to VDD, is it better to add a resistor?

2.nFAULT: If this isn't used, is it allowed to open?

Thank you,
Kazuki Kitajima

    Hi Kitajima-san,

    1. nSLEEP: If this pin connects to VDD, is it better to add a resistor?

    Adding a resistor is optional. It is a system level design choice.
    The nSLEEP pin can be directly connected to a 3.3V or 5V supply.
    Some system designers prefer to place a current limiting resistor to protect against accidental shorts at the pins.

    2.nFAULT: If this isn't used, is it allowed to open?

    Yes, it is allowed to leave nFAULT open.
