Hello

i think TPS3813 family starts watchdog time after starting up Reset signal.
Even if this device is never input watchdog pulse from the CPU after starting up reset signal, does it reset to the CPU?

Best regards,

Hi Yokota-san,

The upper boundary of the watchdog is active when the /RESET signal goes high. Only the first lower boundary is disabled. If a WDI pulse is not received before the upper boundary is reached, /RESET will transition low resetting the CPU.

Very Respectfully,

Ryan
