UCC21220ADR from Texas Instruments, 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 | Input signal for channel A with TTL/CMOS compatible threshold; internally pulled low if left open. |
| 2 | INB | input | Input signal for channel B with TTL/CMOS compatible threshold; internally pulled low if left open. |
| 3 | VCCI | power_in | Primary-side input supply voltage, 3 to 5.5 V range; must be locally decoupled to GND with low ESR/ESL capacitor. |
| 4 | GND | power_in | Primary-side ground reference for all primary-side signals. |
| 5 | DIS | input | Disable input; pull high or leave open to disable both outputs, ground to enable; internally pulled high if left open. |
| 6 | NC | unconnected | No internal connection. |
| 7 | NC | unconnected | No internal connection. |
| 8 | VCCI | power_in | Primary-side input supply voltage, internally shorted to pin 3. |
| 9 | VSSB | power_in | Secondary-side ground reference for channel B driver. |
| 10 | OUTB | output | Channel B driver output, sources 4 A peak and sinks 6 A peak; connect to FET or IGBT gate. |
| 11 | VDDB | power_in | Secondary-side power for driver B, 6.5 to 25 V range for 5V UVLO version; must be locally decoupled to VSSB with low ESR/ESL capacitor. |
| 12 | NC | unconnected | No internal connection. |
| 13 | NC | unconnected | No internal connection. |
| 14 | VSSA | power_in | Secondary-side ground reference for channel A driver. |
| 15 | OUTA | output | Channel A driver output, sources 4 A peak and sinks 6 A peak; connect to FET or IGBT gate. |
| 16 | VDDA | power_in | Secondary-side power for driver A, 6.5 to 25 V range for 5V UVLO version; must be locally decoupled to VSSA with low ESR/ESL capacitor. |
