Hi,

I'm trying to test the Evaluation Board DRV8353RS-EVM. From Start everything was Ok until i connected the BLDC-Motor to the board.

The gate driver tried to identify the Motor parameters, but after about 30 seconds it didn't work anymore.

Then n-fault-LED lights up and the fault is Indicates overcurrent on phase A sense amplifier (DRV8353xS).


Did anyone see have the fault ?  is it still posible to resolve this problem?

Thanks for your help!

Best regard,

Hoang
