DRV8353R: Buck disable

Part Number: DRV8353R
Other Parts Discussed in Thread: LM5008, LM5008A

When VIN =12V(BUCK's bias power) and VM = VDRAIN = 0V, is the internal DC/DC (LM5008) able to be disable by RT/ST pin? and at the same time the gate drivers are shutdown, correct?

Hey Brian,

When the LM5008A is shut down using the RT/SD pin, the VCC bypass switch is shut off regardless of the voltage at VIN. The VM/drain voltage should not affect this since the buck is powered separately.
