Dear,
We use DRV8837C to drive valve. When the power is shut down, DRV8837C need to keep working to close valve, so we use a 3.3F/5.5V capacitance to maintain power. We do an experiment: valve rotates forward for 200ms and then reverse for 100ms, do it for 10 times. Then we find that the waveform of IN1/IN2/OUT1/OUT2/SLEEP all have pulse, so why the waveform have pulse? What can we do to avoid it? I am waiting your reply, than you.
Note: The control code of DRV8837C and SLEEP waveform are shown as follows.
