LM74700-Q1: LM74700-Q1

Part Number: LM74700-Q1

Hi,

we use LM74700-Q1 as primary power supply of our product to connect car 24V battery. It must pass the ISO7637-2 transient emission test, and the voltage waveform is shown in the figure below. The test result is passed (TVS is added to the 24V power line). We measured the waveform of the GATE pin and the result shows that the maximum voltage on the GATE pin of the LM74700-Q1 is -60V. The datasheet shows that the maximum voltage between GATE and ANODE is 15V. So is -60V from GATE pin to GND acceptable? Thanks!
