V
DD
Positive gate drive supply
Locally decouple to V
SS using low ESR/ESL capacitor located
as close to IC as possible.

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.

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.
