Function

1

LIN

I

Low-side driver logic input (active low)

2

I/O

Shutdown logic input (active low)/open-drain

comparator output

3

HIN

I

High-side driver logic input (active high)

4

VCC

P

Lower section supply voltage

5

DT

I

Deadtime setting

6

SGND

allows omitting the “bleeder” resistor connected between the gate and the source of the external MOSFET

normally used to hold the pin low.

When the SD is set low, gate driver outputs are forced low and assure low impedance.

O

Low-side driver output

9

CP-

I

Comparator negative input

10

CP+

I

Comparator positive input

11

NC

Not connected

12

OUT

P

High-side (floating) common voltage

13

O

High-side driver output

14

BOOT

P

Bootstrapped supply voltage
