TPS1H100-Q1: power on sequence between PIN3 IN and PIN12 DIAG_EN

Part Number: TPS1H100-Q1

Dear team,

Is there a timing requirement for PIN3 IN and PIN12 DIAG_EN? Is there a problem with pulling PIN12 high and then pulling PIN3 high?

Thanks & Best Regards,

Sherry

    Hi Sherry,

    Thanks for reaching out on E2E!

    There is no timing requirement for PIN 3 (IN) and PIN 12 (DIAG_EN). They can both be pulled high at the same time. However, f you want to read the CS pin, you will have to wait the CS settling time from DIAG enabled/disabled which is 10us located in the timing requirements section (6.6) of the datasheet.

    Best Regards,

    Elizabeth
