TPS7A63-Q1: TPS7A6350 Enable pin level question

Mike Jung

Part Number: TPS7A63-Q1

Dear TI engineer

My customer has question for TPS7A6350-Q1 enable pin level.

In D/S,

customer test result is

low level : about 1.35V, high level : about 1.7V

first of all, why is it so much better than the stated value?

is this level too high or low, even if it is referred to as variation for logic input?

they are asking for clarification of the exact reason.

Best regards.

    The datasheet for the Enable low has a max spec at 0.8V, which means, the measured threshold the part turns off will be higher than 0.8V. If the voltage on enable is lower than 0.8V, it's guaranteed to be off (logic low). For the logical high spec, it has a minimum 2.5V, the measured threshold will be lower than 2.5V. This guarantees if the Enable is higher than 2.5V, it will be a logical higher.
