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.

close to IC as possible.
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.
Connect to gate of high side MOSFET with short low inductance
path.
Connect to bootstrap capacitor negative terminal and source of high
side MOSFET.
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.
Logic 1 equals High Side ON and Low Side OFF. Logic 0 equals
High Side OFF and Low Side ON.
All signals are referenced to this ground.
Connect to the gate of the low side MOSFET with a short low
inductance path.
