MCT8316Z: Brake functionality

Part Number: MCT8316Z

Hello, we are using the MCT8316Z0R.

Our team noticed that the brake function can be enabled using both a hardware pin and setting a register over SPI.

Can you confirm that the brake pin has no use in the case that we use SPI? Are there any drawbacks to this?

If we plan to not use the hardware pin and there is a 100k PD, can we either drive it low or leave it floating?

  • Hi Daniel,

    your understanding is correct, on MCT devices if you use serial communication to configure the brake function, the device will use that config and ignore the BRAKE hardware pin input. You can pull down the pin in this case.
