Part Number:DRV8305-Q1
Dear, Sir.
My customer would like to monitor nFAULT=Low to High changing status during power-up
and then, start SPI communication for resister setting.
So I would like to make sure several as below. Please give your advice.
1. nFAULT Delay, across PVDD_UVLO2 to nFAULT=>High.
The situation is diffrent, but tPD, E-SD is defined as max. 1us.
I guess max. 1us would be enough as this kind of delay.
How do you think?
2. tSPI_READY is defined as max. 10ms. It is after PVDD>VPVDD_UVLO1.
The customer will monitor the change state nFAULT Low to High.
I guess max. 10ms delay would be safer starting SPI communication.
How do you think?
Best Regards,
H. Sakai
