Connect the positive terminal of the bootstrap HB 2 2 I capacitor to HB and the negative terminal to HS. The bootstrap capacitor should be placed as close to the IC as possible. High-side driver control input. The LM5100A/B/C inputs have CMOS type thresholds. HI 5 7 I The LM5101A/B/C inputs have TTL type thresholds. Unused inputs should be tied to ground and not left open. High-side gate driver output. Connect to the gate of high-side MOSFET with a short, HO 3 3 O low inductance path. High-side MOSFET source connection. Connect to the bootstrap capacitor negative HS 4 4 — terminal and the source of the high-side MOSFET. Low-side driver control input. The LM5100A/B/C inputs have CMOS type thresholds. LI 6 8 I The LM5101A/B/C inputs have TTL type thresholds. Unused inputs should be tied to ground and not left open. Low-side gate driver output. Connect to the gate of the low-side MOSFET with a LO 8 10 O short, low inductance path. Positive gate drive supply . Locally decouple to VSS using low ESR/ESL capacitor VDD 1 1 I located as close to the IC as possible. VSS 7 9 — Ground return. All signals are referenced to this ground. TI recommends that the exposed pad on the bottom of the package is soldered to EP(2) — ground plane on the PC board, and that ground plane should extend out from beneath the IC to help dissipate heat. (1) For WSON-10 package, pins 5 and 6 have no connection. (2) Exposed pad is not available on the 8-pin SOIC package. 4 Submit Documentation Feedback Copyright © 2006–2015, Texas Instruments Incorporated Product Folder Links: LM5100A LM5100B LM5100C LM5101A LM5101B LM5101C |
