Part Number: TPS3852

Hi Sir,

I would like to know the behavior of TPS3852.

Suppose that WDI does not have negative-edge within t_RST + t_WDU, will RESET# or WDO pull LOW?

Thank you

Hi Jim,

If the WDI pulse is not issued before tWDU then WDO will be asserted (low). The RESET is determined by VDD in the TPS3852, when VDD is greater than the threshold RESET will be high.

Best Regards,
Mark
