Pin Functions

PIN DESCRIPTIONunder APPLICATION INFORMATION
NO. NAME
SOIC WSON(1)
1 1 VDD Positive gate drive supply Locally decouple to VSS using low ESR/ESL capacitor located as close to IC as possible.
2 2 HI High side control input The LM5107 HI input is compatible with TTL input thresholds. Unused HI input should be tied to ground and not left open
3 3 LI Low side control input The LM5107 LI input is compatible with TTL input thresholds. Unused LI input should be tied to ground and not left open.
4 4 VSS Ground reference All signals are referenced to this ground.
5 5 LO Low side gate driver output Connect to the gate of the low side N-MOS device.
6 6 HS High side source connection Connect to the negative terminal of the bootstrap capacitor and to the source of the high side N-MOS device.
7 7 HO High side gate driver output Connect to the gate of the low side N-MOS device.
8 8 HB High side gate driver positive supply rail 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.
(1) For WSON package it is recommended that the exposed pad on the bottom of the LM5107 be soldered to ground plane on the PCB board and the ground plane should extend out from underneath the package to improve heat dissipation.
