IR44273LTRPBF

JSMSEMI · Gate Drivers · SOT-23-5

IR44273LTRPBF from JSMSEMI, in a SOT-23-5. 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 IN input Logic input of the gate driver, CMOS Schmitt-trigger and 3.3 V compatible, in-phase with OUT, with VIN range 0 V to VCC.
2 COM power_in Ground reference pin; all voltage ratings are referenced to COM.
3 OUT output Gate drive output (2 A source/2 A sink) swinging 0 V to VCC, tied internally with pin 4.
4 OUT output Gate drive output (2 A source/2 A sink) swinging 0 V to VCC, a second OUT pin shared with pin 3.
5 VCC power_in Supply voltage pin, recommended 5.0 V to 20 V, absolute maximum 25 V, with UVLO thresholds of 4.0 V rising and 3.9 V falling.

CAD (KiCad official)

  • Symbol: IR44273LTRPBF
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: ir44273ltrpbf-etched.step / ir44273ltrpbf-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ir44273ltrpbf.step / ir44273ltrpbf.glb are the bare package body.

Provenance
