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

LM5101ASD 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, recommended 9 V to 14 V with absolute maximum 18 V to VSS; decouple locally to VSS with a low ESR/ESL capacitor placed close to the IC.
2 HB power_in High-side gate driver bootstrap supply; recommended HB is VHS + 8 V to VHS + 14 V, with absolute maximum HB to HS of 18 V, and the bootstrap capacitor should sit as close to the IC as possible.
3 HO output High-side gate driver output, to be connected to the high-side MOSFET gate by a short, low-inductance path; absolute range is VHS − 0.3 V to VHB + 0.3 V.
4 HS passive High-side MOSFET source and bootstrap negative return; recommended HS is −1 V to 100 V with HS slew rate below 50 V/ns, and absolute HS to VSS is −5 V to 100 V.
5 NC unconnected No connection on the 10-pin WSON package.
6 NC unconnected No connection on the 10-pin WSON package.
7 HI input High-side driver control input with TTL thresholds on the LM5101A; absolute range is −0.3 V to VDD + 0.3 V and unused inputs must be tied to ground, not left open.
8 LI input Low-side driver control input with TTL thresholds on the LM5101A; absolute range is −0.3 V to VDD + 0.3 V and unused inputs must be tied to ground, not left open.
9 VSS power_in Ground return; all signals are referenced to this pin.
10 LO output Low-side gate driver output, to be connected to the low-side MOSFET gate by a short, low-inductance path; absolute range is −0.3 V to VDD + 0.3 V.
11 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
