using low ESR/ESL capacitor located
as close to IC as possible.
The LM5109 HI input is compatible with TTL input thresholds.
Unused HI input should be tied to ground and not left open
The LM5109 LI input is compatible with TTL input thresholds.
Unused LI input should be tied to ground and not left open.
All signals are referenced to this ground.
Connect to the gate of the low side N-MOS device.
Connect to the negative terminal of the bootstrap capacitor
and to the source of the high side N-MOS device.
Connect to the gate of the low side N-MOS device.
Connect the positive terminal of the bootstrap capacitor to HB
and the negative terminal of the bootstrap capacitor to HS.
The bootstrap capacitor should be placed as close to IC as
possible.

Note: For LLP-8 package it is recommended that the exposed pad on the bottom of the LM5109 be soldered to ground plane on the PCB board and the
ground plane should extend out from underneath the package to improve heat dissipation.
