LM25101AMX from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Positive gate drive supply; locally decouple to VSS with a low ESR and ESL capacitor located as close to the IC as possible. |
| 2 | HB | power_in | High-side gate driver bootstrap rail; connect the bootstrap capacitor positive terminal to HB and its negative terminal to HS, placed as close to the IC as possible. |
| 3 | HO | output | High-side gate driver output; connect to the gate of the high-side MOSFET with a short, low-inductance path. |
| 4 | HS | power_in | High-side MOSFET source connection; connect to the bootstrap capacitor negative terminal and the source of the high-side MOSFET. |
| 5 | HI | input | High-side driver control input with TTL-type thresholds; unused inputs should be tied to ground and not left open. |
| 6 | LI | input | Low-side driver control input with TTL-type thresholds; unused inputs should be tied to ground and not left open. |
| 7 | VSS | power_in | Ground return; all signals are referenced to this ground. |
| 8 | LO | output | Low-side gate driver output; connect to the gate of the low-side MOSFET with a short, low-inductance path. |
