Texas Instruments · Gate Drivers · WSON-10-EP(4x4)

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).
