DRV8872: There have a figure can't understaand,could you kindly help me explain it?

Jacking Jin

Part Number: DRV8872

Dears,

I read the DRV8872 datasheet, there have a nfault pin to idicate the fault signal, if have OCP or UVLO that the nfault pin will get a low level, but in the figure 13, the out1 is short status, why the nfault pin is high level. Is my understanding mistakes? Thanks very much.

Best regards,

Hi Jacking,

Figure 13 shows the end of an OCP retry time, the OCP deglitch time, and the beginning of the next OCP retry time. nFAULT is low to signal a fault, and high to signal normal operation.

When an OCP occurs, the outputs are disabled for approximately 3ms and then re-enabled.
