TPS1H000-Q1: The minimum capacitance for set tdl2 for DELAY PIN

Jack Li

Part Number: TPS1H000-Q1

Hi team,

According to the datasheet, among the three modes, only latch-off has a shutdown state, and the delay is at least tcl+tdl1+tdl2=

180us+500us+tdl2(Cdelay), what is the minimum capacitance value of Cdelay that can be set to shorten the tdl2 time?

Best Regards!

Hi Jack,

Our team is currently on Thanksgiving Holiday. Kindly expect a delay in response.

Hi Praveen,

My customer want to reduce tdl2, so they try to use a small capacitance as 10pF, then calculate the tdl2≈3.2us. They wonder if this design is ok, is there any risk?

Best Regards!

Hi Jack,

This setup is acceptable. The majority of the delay will be through the internal delay timing.

Thanks,
