TF2103M-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 | Logic and low side supply, recommended 10V to 20V, with VCC undervoltage lockout (positive-going threshold 8.0V to 9.8V, typical 8.9V). |
| 2 | HIN | input | Logic input for the high-side gate driver output, in phase with HO; Schmitt-triggered, compatible with 3.3V logic, recommended input 0V to 5V. |
| 3 | LIN* | input | Logic input for the low-side gate driver output, out of phase with LO; Schmitt-triggered, compatible with 3.3V logic, recommended input 0V to 5V. |
| 4 | COM | power_in | Low-side and logic return. |
| 5 | LO | output | Low-side gate drive output, limited to -0.3V to VCC+0.3V, with 290mA source and 600mA sink pulsed current capability. |
| 6 | VS | power_in | High-side floating supply return, with offset supply voltage limited to VB-24V to VB+0.3V and dVS/dt up to 50 V/ns. |
| 7 | HO | output | High-side gate drive output, limited to VS-0.3V to VB+0.3V. |
| 8 | VB | power_in | High-side floating supply, recommended VS+10V to VS+20V, with absolute maximum of -0.3V to +624V. |
