Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | INA | input | A channel input signal with TTL/CMOS compatible threshold (0 to VCCI V) and internal pull-down to ground. |+| 2 | INB | input | B channel input signal with TTL/CMOS compatible threshold (0 to VCCI V) and internal pull-down to ground. |+| 3 | VCCI | power_in | Primary side power supply input with recommended operating voltage range 3 to 5.5V and UVLO protection. |+| 4 | GND | power_in | Primary side power supply ground pin and reference for all primary side signals. |+| 5 | DISABLE | input | Output disable pin with internal pull-down; high level disables both drivers (response time ~20ns), low or floating enables normal operation. |+| 6 | DT | input | Dead time setting pin; connect to VCCI for simultaneous high outputs, leave floating for <15ns default dead time, or use 500Ω-500kΩ resistor for programmable dead time (tDT ≈ 10×RDT ns). |+| 7 | NC | unconnected | No internal connection. |+| 8 | VCCI | power_in | Primary side power supply input with recommended operating voltage range 3 to 5.5V and UVLO protection. |+| 9 | VSSB | power_in | Secondary side reference ground for driver B and B channel signals. |+| 10 | OUTB | output | Driver B output signal for B channel FET or IGBT gate drive (0 to VDDB V). |+| 11 | VDDB | power_in | Secondary side power supply for driver B with recommended operating voltage range 9.2 to 25V. |+| 12 | NC | unconnected | No internal connection. |+| 13 | NC | unconnected | No internal connection. |+| 14 | VSSA | power_in | Secondary side reference ground for driver A and A channel signals. |+| 15 | OUTA | output | Driver A output signal for A channel FET or IGBT gate drive (0 to VDDA V). |+| 16 | VDDA | power_in | Secondary side power supply for driver A with recommended operating voltage range 9.2 to 25V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | 2Pai Semi |+| Package | SOIC-16 |+| Category | Power Management (PMIC) |+| Pins | 16 |++## CAD (KiCad official)++- Symbol: `Pai8233C-S1R`+- Footprint: `Package_SO:SOIC-16_3.9x9.9mm_P1.27mm`+- 3D model: SOIC-16 (KiCad packages3D, STEP)+- 3D model files: `pai8233c-s1r-etched.step` / `pai8233c-s1r-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `pai8233c-s1r.step` / `pai8233c-s1r.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [2Pai Semi datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8590905290373996544) (24 pp, sha256 `ad19699ddf56bda0`, retrieved 2026-09-22, tier: lcsc)+- **Datasheet language:** Chinese.
