Hi Rick Duncan
Thank you for your advice.
Is monitoring the mv voltage the chip's vm pin?
If so, can I configure a simple constant voltage (about 30V) circuit on the VM pin to avoid high voltage on the VM pin?
I understand that this is not related to the difference in MOSFET supply voltage.
We are working to reduce spikes on the motor side for the anode spikes on the SHx pin.
Our circuit is GH, the resistance to GL path is 0 ohm.
However, a small overshoot occurs when the MOSFET is turned on and off.
This appears as noise on the supply power of the entire circuit.
You may be busy, but I would like some advice.
