UCC27518AQDBVRQ1

Texas Instruments · Gate Drivers · SOT-23-5

UCC27518AQDBVRQ1 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 EN input Enable input: driving EN low disables the output regardless of the input state, while EN high or floating enables the output; the datasheet gives typical V_EN-H of 2.1 V and V_EN-L of 1.25 V.
2 GND power_in Ground: all signals are referenced to this pin.
3 IN- input Inverting input of the UCC27518A-Q1: the output is held LOW if IN- is unbiased or floating.
4 OUT output Sourcing and sinking current output of the driver, rated for 4 A pulsed (0.5 µs) and 0.3 A continuous source/sink per the absolute maximum ratings.
5 VDD power_in Supply input: operating range is 4.5 V to 18 V, with an absolute maximum of 20 V (−0.3 V to 20 V).
