The LM5107 HI input is compatible with TTL input thresholds. 2 2 HI High side control input Unused HI input should be tied to ground and not left open The LM5107 LI input is compatible with TTL input thresholds. Unused 3 3 LI Low side control input 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. Connect to the negative terminal of the bootstrap capacitor and to the 6 6 HS High side source connection 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. Connect the positive terminal of the bootstrap capacitor to HB and High side gate driver positive 8 8 HB the negative terminal of the bootstrap capacitor to HS. The bootstrap supply rail 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. 2 Submit Documentation Feedback Copyright © 2004–2013, Texas Instruments Incorporated Product Folder Links: LM5107 |
