DRV8353RS-EVM: DRV GATE OUTPUT ISSUE

veerapandiyan v

Part Number: DRV8353RS-EVM

Hi Friends,

1. INHx and INLx = 0 (Low) GHx Output is =15 V GLx Output is =0 V

2. INHx = 0 (Low) and INLx = PWM GHx Output is =15 V GLx Output is = PWM Output is Correct

3. INHx = PWM and INLx = PWM GHx Output is =26V GLx Output is = PWM Output is Correct

Thanks

Hi Veerapandiyan,

Thank you for posting to the Motor Drivers forum!

The behavior that you are seeing is correct as the GHx floats at VM supply voltage due to LS MOSFET being off.
