I have an application, where I need SIL2, that means one safety channel is required. I use a STM32F7 with integrated
safety features, compatible to SIL2 and now the safety channel needs to be designed together with the DRV8350F.
From the datasheet it is possible, to separate VM and VDRAIN, that means, I can disconnect VM to disable the gate power
for the MOSFETs, but there I have some questions. When VM is disconnected and VDRAIN has still power, are the
gate voltages pulled to GND? Further, can I use a PMOS to disconnet VM from VDRAIN to implement a STO and if so,
what is the current raiting for VM?
