Pai8233C-S1R from 2Pai Semi, in a SOIC-16. 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. |
