RE: PWM Polarity Inverting Circuit for TEC module using DRV8432 in parallel full bridge mode

Hi,

Sorry for the incomplete thread.

It showed a nFAULT for 6A current @ 15V for a few seconds. It means it is showing Overcurrent at 6A( OC_adj = 24Kohm - 10.7A) itself why it is malfunctioning. Any other thing missing.

Now If I try to drive it with (PVDD) 10V or other , DRV8432 is becoming too hot and no voltage(showing 0V) at the output though there are inputs(PWMs, GVDD, PVDD..Everything is there). nFault, nOtw are also at high pulse.

Whether DRV8432 is died or if it works fine then why doesn't it produce outputs for inputs.

Any help will be appreciated!

Thanks
Sai
