Pin Description

VPP1

Positive high voltage supply.

VPP2

Positive gate voltage supply. Generated by an internal linear regulator. A 25V, 100nF capacitor should be

connected between VPP2 and VPP1.

VNN1

Negative high voltage supply.

VNN2

Negative gate voltage supply. Generated by an internal linear regulator. A 25V, 100nF capacitor should be

connected between VNN2 and VNN1.

VDD

Logic supply voltage.

SGnd

Low voltage logic ground.

PGnd

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.

NIN

Logic control input. When mode is high, logic input high turns ON the external high voltage N-channel MOSFET.

Internally pulled low.

ENABLE

Logic enable input. Logic high enables IC. Internally pulled low.

MODE

Logic mode input. 0=single-control; 1=dual-control. When MODE is high, NIN and PIN independently control NOUT

and POUT, respectively. When MODE is low, NIN controls both outputs in a complementary manner.

(See Truth Table)

FAULT

Logic output. Fault is at logic low when either current limit sense pin, VPsen or VNsen, is activated. Remains

active until overcurrent condition clears or ENABLE=0 or RESET=0.

RESET

Power-on reset. A capacitor connected between this pin and ground determines the delay time between application

of VDD and when the device outputs are enabled. Low leakage tantalum recommended.

DEADBAND

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.

VPgate

Gate drive for external P-channel MOSFET.

VNgate

Gate drive for external N-channel MOSFET.

VPsen

Pulse by pulse over current sensing for P-Channel MOSFET.

VNsen

Pulse by pulse over current sensing for N-Channel MOSFET.
