Part Number: TPS3431-Q1

Hi Sir,

The datasheet specify the Typ. "minimum WDI pulse duration" is 50ns.

We would like to know the Min. and Max. pulse duration requirement for WDI.

Thanks,

Hi Yulung,

We do not specify a datasheet min/max for the minimum WDI pulse duration. However, applying a 100ns or greater pulse should be more than sufficient to recognize any WDI transitions.

Thanks,
Joshua
