TF2108A-3AS

TFSS · Gate Drivers · PDIP-8

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).
