LM5101AMR

Texas Instruments · Gate Drivers · SO-8

LM5101AMR from Texas Instruments, in a SO-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, recommended 9 V to 14 V with an absolute maximum of 18 V to VSS, and should be locally decoupled to VSS with a low ESR/ESL capacitor placed as close to the IC as possible.
2 HB power_in High-side gate driver bootstrap supply; the bootstrap capacitor positive terminal connects to HB and negative terminal to HS, placed as close to the IC as possible, with HB to HS absolute maximum 18 V and recommended HB of VHS + 8 V to VHS + 14 V.
3 HO output High-side gate driver output, to be connected to the high-side MOSFET gate by a short, low-inductance path, with HO limited to VHS − 0.3 V to VHB + 0.3 V.
4 HS passive High-side MOSFET source connection, to be connected to the bootstrap capacitor negative terminal and the high-side MOSFET source, with a recommended range of −1 V to 100 V and HS slew rate below 50 V/ns.
5 HI input High-side driver control input with TTL thresholds on the LM5101A, and unused inputs should be tied to ground and not left open.
6 LI input Low-side driver control input with TTL thresholds on the LM5101A, and unused inputs should be tied to ground and not left open.
7 VSS power_in Ground return to which all signals are referenced, and the exposed pad should be soldered to the ground plane.
8 LO output Low-side gate driver output, to be connected to the low-side MOSFET gate by a short, low-inductance path, with LO limited to −0.3 V to VDD + 0.3 V.

CAD (KiCad official)

  • Symbol: LM5101AMR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SO-8 (KiCad packages3D, STEP)
  • 3D model files: lm5101amr-etched.step / lm5101amr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm5101amr.step / lm5101amr.glb are the bare package body.
