CSD23203W: The use of CSD23203

Part Number: CSD23203W

Hi Team!

The customer used an mcu to control CSD23203 and found that the GPIO voltage which controlled the gate of CSD23303 dropped to about1V. And they tested the current of gate which was 1A. 

I wanted to do a simulation to test the current of gate, but I am no familiar with the PSPICE. Could you share a simulation file which can shows the current of the gate. And did you have any comments about this phenomenon?
