DRV8432 EVM 11V output

Hi,

I just received a DRV8432 EVM and I tried the board like this:

- 12V 3A power supply ( 12.5V measured) for gates

- 24V 5A power supply ( 25V measured)

- PWM input from TI launchpad digital HIGH and 3.3V from internal (both ways)

- FAULT and OTW 3.3V

- RESET Switches on HIGH

- On PWMA test pin is 3.5V, but the output is 11V instead of 24V what I'm using.

- M functions on low all.

I tried with small load, I put a 22K resistor between GND and OUPUT_A and now the output is 4.8V .

Any ideas why the EVM is not working properly ?

Thank you,

Andy
