TF0227-TAH

TFSS · Gate Drivers · SOIC-8

TF0227-TAH from TFSS, in a SOIC-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 NC unconnected No Connect pin; the datasheet assigns it no function.
2 INA input Logic input for the A phase, in phase with OUTA; VIH min 2.4 V, VIL max 0.7 V, with VIN rated 0 V to 5 V.
3 COM power_in Supply return for the driver.
4 INB input Logic input for the B phase, in phase with OUTB; VIH min 2.4 V, VIL max 0.7 V, with VIN rated 0 V to 5 V.
5 OUTB output Gate driver output for the B phase, swinging between 0 V and VCC per the recommended operating conditions.
6 VCC power_in Low-side supply input; recommended operating range 4.5 V to 18 V, absolute maximum -0.3 V to +22 V.
7 OUTA output Gate driver output for the A phase, swinging between 0 V and VCC per the recommended operating conditions.
8 NC unconnected No Connect pin; the datasheet assigns it no function.

CAD (KiCad official)

  • Symbol: TF0227-TAH
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: tf0227-tah-etched.step / tf0227-tah-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); tf0227-tah.step / tf0227-tah.glb are the bare package body.
