TPS745-Q1: VEN(HI): EN VIH max

Haury Zhou

Part Number: TPS745-Q1

Tool/software:

Hi team,

Considering the following thread and the EN threshold vs. temp curve. I think the max value of VEN(HI) should be 1.0V not the min value is, right?

Similarly, the min value of VEN(LO) should be 0.3V not the max value is, right?

Hey,

I can see your confusion. 1V is the minimum value we recommend applying to the EN pin in order to enable the LDO, you can go higher than 1V. While the 0.3V is the maximum value that can be applied for the LDO to be disabled without risk of a transient/noise enabling it.

Hope this helps.

Hi Vahnroy,

I suggest to revise the datasheet. Current description is confusing for customer.
