UCC28089D

Texas Instruments · AC-DC Controllers And Regulators · SOIC-8

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.
