TPS745-Q1: PG terminal

Part Number: TPS745-Q1

Tool/software:

When the EN terminal goes from H to L, does the PG terminal immediately go from H to L without waiting for the OUT output voltage to drop below 90%?

    Hello,

    We currently don't have tps745-q1 on hand but I have gone ahead and ordered a sample to measure this. Please allow 5-6 business day for a response.

    Hello,

    I have gone and tested this inquiry for you.

    The images are the same test with different scaling. In regards to the OUT output voltage, you can see that PG goes from H to L before 90% voltage drop (first image) and it seems that there is about a 100ns delay from when the EN pin goes from H to L, the PG pin goes from H to L (second image).

    Hope this was helpful,

    Jorge
