TPS22964C: TPS22964C EN falling edge trigger

Part Number: TPS22964C

Tool/software:

Hi Team

Since we need to measure the LSW T-off time, but we find the Vout(+VREG_CONN_IN=5V) is fall when enable is about 0.85V in our application,

It’s not mapping the datasheet VIL value 0.6V

Normal behavior for other rail application, only occur Vout fall>En VIL on this rail

abnormal waveform:

Normal waveform:

I think it would relate to EN falling rate. do you think it's normal to influence the trigger point?
