# TF2101M-TAH

**TFSS** · Gate Drivers · SOIC-8

TF2101M-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 | VCC | power_in | Low-side and logic fixed supply, 10V to 20V recommended operating range (24V absolute maximum), with undervoltage lockout. |
| 2 | HIN | input | Logic input for high-side gate driver output (HO), in phase; CMOS/TTL compatible Schmitt trigger with internal pull-down. |
| 3 | LIN | input | Logic input for low-side gate driver output (LO), in phase; CMOS/TTL compatible Schmitt trigger with internal pull-down. |
| 4 | COM | power_in | Low-side return (ground) for the low-side driver and logic. |
| 5 | LO | output | Low-side gate drive output, swings from COM to VCC. |
| 6 | VS | power_in | High-side floating supply return, operating up to 600V offset. |
| 7 | HO | output | High-side gate drive output, swings from VS to VB. |
| 8 | VB | power_in | High-side floating supply, VS+10V to VS+20V recommended, up to 624V absolute maximum. |
