LM5101AMX

Texas Instruments · Gate Drivers · SOIC-8

LM5101AMX from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; 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 using low ESR/ESL capacitor located as close to the IC as possible.
2 HB power_in High-side gate driver bootstrap supply; connect positive terminal of bootstrap capacitor to HB and negative terminal to HS, with capacitor placed close to the IC.
3 HO output High-side gate driver output; connect to the gate of high-side MOSFET with short, low inductance path.
4 HS power_in High-side MOSFET source connection; connect to bootstrap capacitor negative terminal and the source of the high-side MOSFET.
5 HI input High-side driver control input with TTL type thresholds for LM5101A/B/C; unused inputs must be tied to ground and not left open.
6 LI input Low-side driver control input with TTL type thresholds for LM5101A/B/C; unused inputs must 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 low-side MOSFET with short, low inductance path.
