TF2108A-3AS from TFSS, in a PDIP-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 (absolute maximum 24V). |
| 2 | HIN | input | Logic input for the high-side gate driver output, in phase with HO; Schmitt-triggered with internal pull-down, 3.3V capable. |
| 3 | LIN* | input | Logic input for the low-side gate driver output, out of phase with LO; Schmitt-triggered with internal pull-down, 3.3V capable. |
| 4 | COM | power_in | Low-side return (ground reference for the LO output). |
| 5 | LO | output | Low-side gate drive output, swings from 0V to VCC. |
| 6 | VS | power_in | High-side floating supply return, operates 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 (absolute maximum 624V). |
