How to connect the Gate Driver Board (CGD1200HB2P-BM2) with the Power Module CAS120M12BM2

Zakir_Hasan

I am trying to generate PWM signal and gate pulses the CGD1200HB2P-BM2 gate drive board with the half bridge module (CAS120M12BM2) . I am supplying 0-5V input signals and 12V power to the board, however the output is not showing any pulses and getting stuck at high or low rail (-5V or + 20V).

No fault lights are tripping. The overcurrent protection pin is connected to the positive side of the half bridge (CAS120M12BM2). There is no voltage applied to the lf bridge during this test (Vds = 0). Reset is pulled low. PWM-EN are pulled high (5V).

How can I generate gate pulse? Please let me know.

Thank you.
