11

V

DD

Positive gate drive supply Locally decouple to V

close to IC as possible.

2

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

3

HO

High side gate driver

output

Connect to gate of high side MOSFET with short low inductance

path.

4

4

HS

High side MOSFET

source connection

Connect to bootstrap capacitor negative terminal and source of high

side MOSFET.

5

7

RT

Deadtime programming

pin

Resistor from RT to ground programs the deadtime between high

and low side transitions.The resistor should be located close to the

IC to minimize noise coupling from adjacent traces.

6

8

IN

Control input

Logic 1 equals High Side ON and Low Side OFF. Logic 0 equals

High Side OFF and Low Side ON.

79

V

SS

Ground return

All signals are referenced to this ground.

8

10

LO

Low side gate driver

output

Connect to the gate of the low side MOSFET with a short low

inductance path.

Note: For LLP-10 package, it is recommended that the exposed pad on the bottom of the LM5100 / LM5101 be soldered to ground plane on the PC board,

and the ground plane should extend out from beneath the IC to help dissipate the heat. Pins 5 and 6 have no connection.
