UCC28089D from Texas Instruments, in a SOIC-8. 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 | SYNC | output | Oscillator-synchronization output that is logic high (VDD) during the oscillator discharge time and logic low (GND) at other times, and is active only while OUTA and OUTB are active; it is held low during under-voltage lockout and over-current shutdown. |
| 2 | DIS | input | Separate oscillator timing-capacitor discharge pin that lets the dead time be programmed externally; the analog input range is -0.3 V to VDD + 0.3 V and not to exceed 5 V. |
| 3 | CT | input | Oscillator timing-capacitor connection, with a recommended timing capacitor range of 100 pF to 100,000 pF. |
| 4 | CS | input | Current-sense input where an over-current shutdown is triggered when the voltage rises above 0.75 V (electrical table gives a 0.650 V to 0.800 V shutdown threshold, 0.725 V typical). |
| 5 | GND | power_in | Ground pin to which analog and digital signals are referenced and through which the output drivers return current. |
| 6 | OUTB | output | Driver output capable of sinking 1 A and sourcing 0.5 A (absolute maximum peak currents), alternating with OUTA. |
| 7 | OUTA | output | Driver output capable of sinking 1 A and sourcing 0.5 A (absolute maximum peak currents), alternating with OUTB. |
| 8 | VDD | power_in | Power input for the device, with recommended supply range of 8.5 V to 14 V (IDD < 10 mA) and an absolute maximum of 15 V. |
