V

DD

Positive gate drive supply

Locally decouple to V

as close to IC as possible.

2

2

HB

High side gate driver

bootstrap rail

Connect the positive terminal of the bootstrap capacitor to HB

and the negative terminal to HS. The Bootstrap capacitor

should be place as close to IC as possible.

3

3

HO

High side gate driver output

Connect to gate of high side MOSFET with a short low

inductance path.

4

4

HS

High side MOSFET source

connection

Connect to bootstrap capacitor negative terminal and the

source of the high side MOSFET.

5

7

HI

High side driver control input

The LM5100 inputs have CMOS type thresholds. The LM5101

inputs have TTL type thresholds. Unused inputs should be

tied to ground and not left open.

6

8

LI

Low side driver control input

The LM5100 inputs have CMOS type thresholds. The LM5101

inputs have TTL type thresholds. Unused inputs should be

tied to ground and not left open.

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.
