Hi Nick，

Test condition：Contact 4KV ESD test，Manual discharge，Frequency is 1S.

IC is not damaged, and the IC can resume normal operation after the input power is disconnected.If the input power supply is always present, the IC cannot resume normal operation.

By the way，Is the ESD test below applying 2KV to each PIN of the IC?

Hi,

Where is the ESD test applied that causes the device to not have an output voltage? 

Yes the 2kV ESD test is applied to each pin of the IC.

Regards,

Nick
