**Texas Instruments** · Power Management - Specialized · SOIC-8

UCC39002DR 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 | CS- | input | Current-sense amplifier inverting input with voltage range from -0.3V to VDD + 0.3V. |
| 2 | CS+ | input | Current-sense amplifier noninverting input with voltage range from -0.3V to VDD + 0.3V. |
| 3 | VDD | power_in | Power supply input with operating voltage range 4.575V to 13.5V; bypass with 0.1µF to 1µF capacitor. |
| 4 | GND | power_in | Ground; reference and power ground for all device functions. |
| 5 | ADJ | output | Adjust amplifier output; buffered error-amplifier output, must be ≥ VEAO + 1V, maximum sink current 6mA. |
| 6 | EAO | output | Load-share error amplifier output (transconductance type) with voltage range 0V to VDD - 1.7V. |
| 7 | LS | bidirectional | Load-share bus with bidirectional driver and receiver, operating voltage range 0V to VDD - 1.7V. |
| 8 | CSO | output | Current-sense amplifier output with voltage range 0V to VDD - 1.7V. |
