Part Number: LP8733

Hello Expert,

For the below PMIC's we are looking for PGOOD de-assert timing when it senses fault.

1. LP873349RHDRQ1

2. LP875651RNFRQ1

3. LP87521FRNFRQ1

As per the datasheet PGOOD is configurable using OTP. Could you please help us with this timings configured in OTP?

Hi Bala,

Are you looking for the typical time it takes for PGOOD to de-assert when a fault is detected on one of the output power rails? Or are you looking for the time it takes PGOOD to be asserted HIGH after OTP is loaded after a power cycle or reset?

Regards,

James
