Hi Kento,

We do not have a recommended power off sequence. However, this is dependent on the load being driven. For example, a motor could generate enough BEMF voltage while decelerating to pump the VM voltage and potentially violate the abs max rating of the device. This can be mitigated with sufficient bulk capacitance on VM or decelerating the motor before shutting down the device.

Joshua
