UCC27425DR from Texas Instruments, in a SOIC-8. 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 | ENBA | input | Enable input for driver A; internally pulled up to VDD with 100 kΩ resistor; logic compatible threshold with hysteresis; output forced to low when disabled. |
| 2 | INA | input | Input signal for driver A with logic compatible threshold (VIN_H = 1.6 to 2.5 V, VIN_L = 0.8 to 1.5 V); must be tied to VDD or GND if not used. |
| 3 | GND | power_in | Common ground connection; should be connected closely to the source of the power MOSFET being driven. |
| 4 | INB | input | Input signal for driver B with logic compatible threshold (VIN_H = 1.6 to 2.5 V, VIN_L = 0.8 to 1.5 V); must be tied to VDD or GND if not used. |
| 5 | OUTB | output | Driver output B for noninverting channel; capable of providing ±4 A drive current to power MOSFET gate; 20 ns rise time and 15 ns fall time typical with 1.8 nF load. |
| 6 | VDD | power_in | Supply voltage input; operating range 4 V to 15 V; requires low ESR bypass capacitors (100 nF and 220 nF to 10 μF) close to pins. |
| 7 | OUTA | output | Driver output A for inverting channel; capable of providing ±4 A drive current to power MOSFET gate; 20 ns rise time and 15 ns fall time typical with 1.8 nF load. |
| 8 | ENBB | input | Enable input for driver B; internally pulled up to VDD with 100 kΩ resistor; logic compatible threshold with hysteresis; output forced to low when disabled. |
