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. |
