Pin Descriptions

Name

Description

Application Information

1

VDD

Positive gate drive supply

Decouple VDD to VSS using a low ESR/ESL capacitor, placed as

close to the IC as possible.

2

HB

High side gate driver

bootstrap rail

Connect the positive terminal of bootstrap capacitor to the HB pin

and connect negative terminal to HS. The Bootstrap capacitor

should be placed as close to IC as possible.

3

HO

High side gate driver

output

Connect to the gate of high side N-MOS device through a short,

low inductance path.

4

HS

High side MOSFET source

connection

Connect to the negative terminal of the bootststrap capacitor and to

the source of the high side N-MOS device.

5

NC

Not Connected

6

RDT

Dead-time programming

pin

A resistor from RDT to VSS programs the turn-on delay of both the

high and low side MOSFETs. The resistor should be placed close

to the IC to minimize noise coupling from adjacent PC board traces.

7

EN

Logic input for driver

Disable/Enable

TTL compatible threshold with hysteresis. LO and HO are held in

the low state when EN is low.

8

IN

Logic input for gate driver

TTL compatible threshold with hysteresis. The high side MOSFET

is turned on and the low side MOSFET turned off when IN is high.

9

VSS

Ground return

All signals are referenced to this ground.

10

LO

Low side gate driver output

Connect to the gate of the low side N-MOS device with a short, low

inductance path.

NA

EP

Exposed Pad

The exposed pad has no electrical contact. Connect to system

ground plane for reduced thermal resistance.
