Hi  Vincent,

   Pls try to see the two devices: One is TPS3808 with adjustable delay time from 1.25ms-10s; Another is push button Reset device TPS3420.

   may i know why this application need couple minutes delay time ? If so, may be the Timer TPL511 can be consider.

Hi Curly,

thanks for you suggestion.

customer accept TPL50101 after discuss with them.
