    Part Number: DRV8837 Hi team, Here's an issue from the customer may need your help: During the test, the motor was replaced with a resistive load. When the input PWM was low, the OUT1 and OUT2 voltages could not be attributed to 0 V. For example,…

    Naveen, Then that doesn't match any previous theories as the other drivers with much higher Rdson work fine. So, it appears we can rule out Rdson as the culprit. Have you tried any of the other experiments recommended above with altering PWM duty…
