UCC21220ADR

Texas Instruments · Isolators - Gate Drivers · SOIC-16

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.
