# U3216C

**UNI SEMIC** · Gate Drivers · SOP-8

U3216C from UNI SEMIC, in a SOP-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, recommended operating range 5.0 V to 20 V, with UVLO thresholds of 4.8 V (rising) and 4.5 V (falling). |
| 2 | HIN | input | Logic input for the high side gate driver output (HO), in phase; logic input range is 0 to VCC, with VIH minimum 3 V and VIL maximum 0.8 V. |
| 3 | LIN | input | Logic input for the low side gate driver output (LO), out of phase for the U3216C; logic input range is 0 to VCC, with VIH minimum 3 V and VIL maximum 0.8 V. |
| 4 | COM | power_in | Low side return; all absolute voltage parameters in the datasheet are referenced to COM. |
| 5 | LO | output | Low side gate drive output, swinging between 0 V and VCC. |
| 6 | VS | power_in | High side floating supply offset/return, with a recommended range of -6 V to 600 V (logic operational for VS of -6 V to +600 V) and dV/dt limited to 55 V/ns. |
| 7 | HO | output | High side gate drive output, swinging between VS and VB. |
| 8 | VB | power_in | High side floating supply, which must be maintained between VS + 5 V and VS + 20 V (absolute maximum VB 625 V). |

## CAD (KiCad official)

- Symbol: `U3216C`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOP-8 (KiCad packages3D, STEP)
- 3D model files: `u3216c-etched.step` / `u3216c-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `u3216c.step` / `u3216c.glb` are the bare package body.
