TF2190M-TAH from TFSS, 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 | HIN | input | Logic input for high-side gate driver output, in phase with HO. Schmitt-triggered with internal pulldown; TTL/CMOS compatible down to 3.3V (VIH >= 2.5V, VIL <= 0.8V). |
| 2 | LIN | input | Logic input for low-side gate driver output, in phase with LO. Schmitt-triggered with internal pulldown; TTL/CMOS compatible down to 3.3V. |
| 3 | COM | power_in | Low-side and logic return (ground reference for VCC, LO driver, and logic inputs). |
| 4 | LO | output | Low-side gate drive output. Push-pull driver capable of 4.5A typ sink/source, referenced to COM, swings between COM and VCC. |
| 5 | VCC | power_in | Low-side and logic fixed supply. Recommended 10V to 20V; absolute max 24V. UVLO rising threshold typ 8.4V. |
| 6 | VS | power_in | High-side floating supply return (switch-node reference for the high-side driver). Operates from -5V up to +600V relative to COM. |
| 7 | HO | output | High-side gate driver output. 4.5A typ sink/source, referenced to VS, swings between VS and VB. |
| 8 | VB | power_in | High-side floating (bootstrap) supply. Recommended VS+10V to VS+20V; absolute max 624V. UVLO rising threshold typ 8.4V. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 464 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
