Positive high voltage supply.
Positive gate voltage supply. Generated by an internal linear regulator. A 25V, 100nF capacitor should be
connected between V
Negative high voltage supply.
Negative gate voltage supply. Generated by an internal linear regulator. A 25V, 100nF capacitor should be
connected between V
Logic supply voltage.
Low voltage logic ground.
High voltage power ground.
Logic control input. When mode is high, logic input high turns ON the external high voltage P-channel MOSFET.
Internally pulled low.
Logic control input. When mode is high, logic input high turns ON the external high voltage N-channel MOSFET.
Internally pulled low.
Logic enable input. Logic high enables IC. Internally pulled low.
Logic mode input. 0=single-control; 1=dual-control. When MODE is high, N

Logic output. Fault is at logic low when either current limit sense pin, V
active until overcurrent condition clears or ENABLE=0 or RESET=0.
Power-on reset. A capacitor connected between this pin and ground determines the delay time between application
of V
A resistor between this pin and ground sets the ‘break-before-make’ time between output transitions. Applicable
only in single-control mode. For minimum deadtime, a 5.6kΩ resistor to ground should be used. For dual-input
mode, tie to Vdd.
Gate drive for external P-channel MOSFET.
Gate drive for external N-channel MOSFET.
Pulse by pulse over current sensing for P-Channel MOSFET.
Pulse by pulse over current sensing for N-Channel MOSFET.
