Description
Positive high voltage supply.
High voltage power ground.
Low voltage ground.
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.
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.
Active low enable input.
Logic supply voltage.
Negative high voltage supply.
Negative gate voltage supply. Generated by an internal linear regulator. A 0.1µF capacitor should
be connected between VNN2 and VNN1.
Gate drive for external N-channel MOSFET.
Pulse by pulse over current sensing for internal N-Channel MOSFET.
High voltage output. Voltage swings from VPP1 to VNN1.
Pulse by pulse over current sensing for internal P-Channel MOSFET.
Positive gate voltage supply. Generated by an internal linear regulator. A 0.1µF capacitor should
be connected between VPP2 and VPP1.
Gate drive for external P-channel MOSFET.
