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 | COMP | output | COMP is the error amplifier output and the PWM comparator input, with feedback loop compensation applied between this pin and FB, and the internal error amplifier has a current limit. |+| 2 | FB | input | FB is the inverting input of the error amplifier, and its trace should be kept short with minimal stray capacitance for best stability. |+| 3 | CS | input | CS is the input to the current-sense comparators (PWM and overcurrent), connected directly to the MOSFET source sense resistor, with 100 ns internal leading-edge blanking. |+| 4 | RC | input | RC is the oscillator timing pin, where an external resistor from REF and a capacitor to GND set the switching frequency and maximum duty cycle; the datasheet recommends RT of 10 kΩ to 200 kΩ and CT of 100 pF to 1000 pF and says RT must never be below 10 kΩ. |+| 5 | GND | power_in | GND is the reference ground and power ground for all device functions, and the datasheet recommends separating the signal return path from the high-current gate-driver path. |+| 6 | OUT | output | OUT is the high-current power driver output for the power MOSFET gate, capable of peak drive current above ±750 mA (up to ±1 A), and is actively held low when VCC is below the UVLO threshold. |+| 7 | VCC | power_in | VCC is the device bias supply input, normally fed from a low-impedance source through a current-limiting resistor and bypassed to GND with a 0.1 µF ceramic capacitor, with an internal zener clamp of about 13.5 V typical and a 12 V absolute maximum supply rating. |+| 8 | REF | output | REF is the voltage reference for the error amplifier and logic supply, providing 5 V for UCCx813-[0,1,2,4] (4 V for UCCx813-[3,5]), and requires a ceramic bypass capacitor of at least 0.1 µF to GND with a recommended REF output current of 5 mA maximum. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | Power Management (PMIC) |+| Pins | 8 |++## CAD (KiCad official)++- Symbol: `UCC2813DTR-2`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)+- 3D model files: `ucc2813dtr-2-etched.step` / `ucc2813dtr-2-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ucc2813dtr-2.step` / `ucc2813dtr-2.glb` are the bare package body.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/ucc3813-0) (53 pp, sha256 `e691a7fcf4f2163a`, retrieved 2026-10-07, tier: lcsc)+- **Datasheet language:** Chinese.
