P-channel gate voltage supply. Generated by an internal linear regulator. A 0.1µF capacitor should be connected between
PGND and VPP.
Negative high voltage supply.
N-channel gate voltage supply. Generated by an internal linear regulator. A 0.1µF capacitor should be connected between
VNN2 and VNN1.
Logic supply voltage.
Low voltage ground.
High voltage power ground.
Logic control input. When mode is high, logic input high turns OFF output high voltage P-Channel.
Logic control input. When mode is high, logic input high turns ON output high voltage N-Channel.
Logic enable input. Logic low enables IC.
Logic mode input. Logic low activates 200nsec deadband. When mode is low, NIN turns on and off the high voltage N- and
P-Channels. Pin is not used and should be connected to VDD or ground.
High voltage output. Voltage swings from PGND to VNN1.
Pulse by pulse over current sensing for P-Channel MOSFET.
Pulse by pulse over current sensing for N-Channel MOSFET.
Gate drive for external P-channel MOSFET.
Gate drive for external N-channel MOSFET.
