Pin Description
SO-8
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.

Locally decouple to V
as close to IC as possible.
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.
Connect to gate of high side MOSFET with a short low
inductance path.
Connect to bootstrap capacitor negative terminal and the
source of the high side MOSFET.
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.

All signals are referenced to this ground.
Connect to the gate of the low side MOSFET with a short low
inductance path.
