GND disconnection protection

GND disconnection is the disconnection of the module from the reference line. When this condition occurs, the

output channel is turned off regardless of the input status.

When this event occurs, the IC continues working normally until the voltage between VCC and GND pins of the IC

results ≥ VUVOFF. The voltage on the GND pin of the IC rises up to the supply rail voltage level. In case of a GND

disconnection event, a current (ILGND) flows through OUT pin.

For an inductive load, if the GND is disconnected while the output channel is active, the current flows through the

power, which is activated by an active clamp as if the input had been deactivated.
