DRV8870: VM input protection circuit/device

Guru 11160 points
Part Number: DRV8870

Hello,

When my customer turns off the motor power while using the DRV8870, a very large current is generated and sometimes the motor driver burns out.

The current measurement waveform between the power supply and the VM input of the motor driver is as follows.

If there is a recommended protection circuit or IC to prevent this symptom, please recommend it.

Thank you.
