Pin Description

Pin

Name Description

1

VPP1 Positive high voltage supply.

2

PGND High voltage power ground.

3

GND Low voltage ground.

4

MODE

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.

5

PIN Logic control input. When mode is high, logic input high turns off output high voltage P-Channel.

6

NIN Logic control input. When mode is high, logic input high turns on output high voltage N-Channel.

7

EN Active low enable input.

8

VDD Logic supply voltage.

9

VNN1 Negative high voltage supply.

10

VNN2

Negative gate voltage supply. Generated by an internal linear regulator. A 0.1µF capacitor should

be connected between VNN2 and VNN1.

11

NGATE Gate drive for external N-channel MOSFET.

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

13 HVOUT High voltage output. Voltage swings from VPP1 to VNN1.

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

15

PGATE Gate drive for external P-channel MOSFET.

16

VPP2

Positive gate voltage supply. Generated by an internal linear regulator. A 0.1µF capacitor should

be connected between VPP2 and VPP1.
