MCT8329EVM: GVDD

Tool/software:

I am getting a GVDD_UV_Fault.

I checked the GVDD pin, I have connected a 4S battery pack with current voltage at PVDD as 16 Volts, I am able to connect the MCT8329EVM and read and write the registers.

Initially the voltage at GVDD is 13 Volt but as soon as I give speed command through I2C, the GVDD goes to zero and GVDD_UV_Fault is triggered.
