DRV8714-Q1: HW register behaviour

Josef Warta

Part Number: DRV8714-Q1

Hello Team,

Customer has a question regarding Driver DRV871xS.

is it possible that HW registers in DRV are set by environmental influences somehow ( without the SW sending SPI commands)?

Question is FUSA related

Best Regards

Josef.

Hi Josef,

Thank you for your question. Here is case for registers change..

-nSLEEP pin.

If nSLEEP pin goes to low level input, all registers will be reset (default)

-DVDD pin

If DCDD hit threshold level of POR, all registers will be reset(default)

This table is good one for reference. FYI.
