TPS386596: Is it OK for Sense voltage to come up before supply

Dan Andersen

Part Number: TPS386596

Customer is using the TPS386596 to monitor a 3.3V rail that comes up 500ms before the actual supply VDD (separate 3.3V). Is this OK?

What if the VSENSE1 and VDD were the same 3.3V supply?

Thanks,

Dan

Hi Dan,

Sensing the power supply (VDD) for the supervisor is a common application for supervisors; however, there should also not be an issue if the sense voltage comes up before VDD.

Very Respectfully,
Ryan
