F
(with the external shunt resistance and CR connection)
c1 : Normal operation: MOSFET ON and carrying current.
c2 : Short circuit current detection (SC trigger).
c3 : Hard MOSFET gate interrupt.
c4 : MOSFET turns OFF.
c5 : Fault output timer operation starts: The pulse width of the fault output signal is set by the external capacitor C
FO
.
c6 : Input “L” : MOSFET OFF state.
c7 : Input “H”: MOSFET ON state, but during the active period of fault output the MOSFET doesn’t turn ON.
c8 : MOSFET OFF state
