# STGAP2SICS

**STMicroelectronics** · Isolators - Gate Drivers · SO-8-300mil

STGAP2SICS from STMicroelectronics, in a SO-8-300mil. 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 | VDD | power_in | Driver logic supply voltage input, 3.1 to 5.5 V recommended operating range. |
| 2 | IN+ | input | Driver logic input, active high, with TTL/CMOS hysteresis levels (0.62 to 0.70 × VDD). |
| 3 | IN- | input | Driver logic input, active low, with TTL/CMOS hysteresis levels (0.29 to 0.37 × VDD). |
| 4 | GND | power_in | Driver logic ground reference for control section. |
| 5 | VH | power_in | Galvanically isolated gate driver power supply, 14.6 to 26 V (VH vs. GNDISO) with UVLO protection. |
| 6 | GON | output | Gate driver source output with 4 A sink/source capability at 25°C, high impedance during safe state. |
| 7 | GOFF | output | Gate driver sink output with 4 A sink/source capability at 25°C, actively driven low during safe state. |
| 8 | GNDISO | power_in | Isolated ground reference for gate driver outputs on the floating power stage side. |

## CAD (KiCad official)

- Symbol: `STGAP2SICS`
- Footprint: `Package_SO:SO-8_3.9x4.9mm_P1.27mm`
- 3D model: SO-8-300mil (KiCad packages3D, STEP)
- 3D model files: `stgap2sics-etched.step` / `stgap2sics-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `stgap2sics.step` / `stgap2sics.glb` are the bare package body.
