Is it enough to remove power from VM-pin to safely turn off gate-driver?
Problem is that VDRAIN also is supplied from VM
Normal situation is that all logic voltages are already present and that the control loop is only being enabled via VM pin thereafter. But VDRAIN is already present then.
Would it be better to apply VDRAIN and VM at the same timeor does the device not care?
Because they are looking at a safety application it may anyhow be better to do it like this (concerning short between VM and VDRAIN)
Can VDRAIN be left open if nFAULT pin is not going to be used?
Are the control ciruits of VM and VDRAIN separated from each other inside the IC?
thx, Andreas
