PRODUCTION DATA.
PIN | I/O | DESCRIPTION | ||||
---|---|---|---|---|---|---|
NAME | 8 PINS | 10 PINS(1) | ||||
HB | 2 | 2 | I | High-side gate driver bootstrap supply. Connect the positive terminal of the bootstrap capacitor to HB and the negative terminal to HS. The bootstrap capacitor should be placed as close to the IC as possible. | ||
HI | 5 | 7 | I | High-side driver control input. The LM5100A/B/C inputs have CMOS type thresholds. The LM5101A/B/C inputs have TTL type thresholds. Unused inputs should be tied to ground and not left open. | ||
HO | 3 | 3 | O | High-side gate driver output. Connect to the gate of high-side MOSFET with a short, low inductance path. | ||
HS | 4 | 4 | — | High-side MOSFET source connection. Connect to the bootstrap capacitor negative terminal and the source of the high-side MOSFET. | ||
LI | 6 | 8 | I | Low-side driver control input. The LM5100A/B/C inputs have CMOS type thresholds. The LM5101A/B/C inputs have TTL type thresholds. Unused inputs should be tied to ground and not left open. | ||
LO | 8 | 10 | O | Low-side gate driver output. Connect to the gate of the low-side MOSFET with a short, low inductance path. | ||
VDD | 1 | 1 | I | Positive gate drive supply . Locally decouple to VSS using low ESR/ESL capacitor located as close to the IC as possible. | ||
VSS | 7 | 9 | — | Ground return. All signals are referenced to this ground. | ||
EP(2) | — | TI recommends that the exposed pad on the bottom of the package is soldered to ground plane on the PC board, and that ground plane should extend out from beneath the IC to help dissipate heat. |
