LM5101CSD from Texas Instruments, in a WSON-10-EP(4x4). 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 voltage input; locally decouple to VSS using low ESR/ESL capacitor located as close to the IC as possible. |
| 2 | HB | power_in | High-side gate driver bootstrap supply for charging the bootstrap capacitor; connect the positive terminal of the bootstrap capacitor to HB and the negative terminal to HS. |
| 3 | HO | output | High-side gate driver output with 1-A peak output current; connect to the gate of high-side MOSFET with a short, low inductance path. |
| 4 | HS | passive | High-side MOSFET source connection point; connect to the bootstrap capacitor negative terminal and the source of the high-side MOSFET. |
| 5 | NC | unconnected | No internal connection. |
| 6 | NC | unconnected | No internal connection. |
| 7 | HI | input | High-side driver control input with TTL type thresholds for LM5101C; unused inputs should be tied to ground and not left open. |
| 8 | LI | input | Low-side driver control input with TTL type thresholds for LM5101C; unused inputs should be tied to ground and not left open. |
| 9 | VSS | power_in | Ground return; all signals are referenced to this ground. |
| 10 | LO | output | Low-side gate driver output with 1-A peak output current; connect to the gate of the low-side MOSFET with a short, low inductance path. |
| 11 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
