UCC44273DBVR

Texas Instruments · Gate Drivers · SOT-23-5

UCC44273DBVR from Texas Instruments, in a SOT-23-5. 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 IN input Non-inverting PWM input with TTL/CMOS compatible thresholds (typical high 2.2 V, low 1.2 V); operating voltage 0 to 18 V, absolute maximum -6 to 20 V.
2 GND power_in Ground reference for all signals.
3 OUT output Sourcing/sinking driver output with 4-A peak capability at VDD = 12 V; internally connected to pin 4; output voltage range -0.3 to VDD + 0.3 V DC.
4 OUT output Sourcing/sinking driver output with 4-A peak capability at VDD = 12 V; internally connected to pin 3; output voltage range -0.3 to VDD + 0.3 V DC.
5 VDD power_in Bias supply input; operating range 4.5 to 18 V, absolute maximum -0.3 to 20 V.
