  • RE: DRV8424E: Does DRV8424E have inputs deglitch filter (might cause output jitter issue)?

    Could someone at Ti use the DRV8424EVM in PH/EN mode, then input a constant pwm, i.e. 10% pwm duty, then check the outputs to see if the output pwm signal has jittering? I don't want to buy the $100 EVM board just to verify this. Thanks, Brian
