GND disconnection protection

GND disconnection is intended as the disconnection event of the application ground, see

figure below. When this event happens, the IC continues working normally until the voltage

between VCC and GND pins of the IC resu

lts ≥ VUVOFF. The voltage on GND pin of the IC

rises up to the supply rail voltage level. In case of GND disconnection event, a current

(ILGND) flows through OUT pin. Table 8: "Logic inputs" reports IOUT = ILGND for the worst case

of GND disconnection event in case of output shorted to ground.
