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 | CURLIM | input | Programs the primary current limit threshold and determines whether the device latches off or retries after an overcurrent; the voltage must stay below 350 mV for a restart. |+| 2 | VREF | power_out | 5.1 V ±1% trimmed reference output with 5 mA maximum available current, which must be bypassed to GND with at least a 0.1-µF ceramic capacitor. |+| 3 | CS-- | input | Inverting input of the 3× differential current sense amplifier. |+| 4 | CS+ | input | Non-inverting input of the 3× differential current sense amplifier. |+| 5 | NI | input | Non-inverting input of the error amplifier. |+| 6 | INV | input | Inverting input of the error amplifier. |+| 7 | COMP | output | Output of the error amplifier and input of the PWM comparator; zero duty cycle is commanded by externally forcing COMP to GND. |+| 8 | CT | input | Oscillator timing capacitor connection, charged by the RT current and discharged to GND through a 2.5-mA sink to set dead time. |+| 9 | RT | input | Oscillator timing resistor connection, nominally 1.25 V; the mirrored current is limited to 100 µA so RT must be greater than 12.5 kΩ. |+| 10 | SYNC | bidirectional | Bidirectional TTL-compatible synchronization pin that outputs a pulse during oscillator dead time, and becomes an input disabling the internal oscillator when RT is forced above 4.4 V. |+| 11 | AOUT | output | High-current gate drive for the external MOSFET, with duty cycle variable from 0% to 50%. |+| 12 | GND | power_in | Reference ground and power ground for all functions of the device. |+| 13 | VC | power_in | Input supply connection for the FET drive outputs, with an input range of 2.5 V to 15 V, which should be capacitively bypassed. |+| 14 | BOUT | output | High-current gate drive for the external MOSFET, alternating with AOUT. |+| 15 | VIN | power_in | Input supply connection for the device, internally limited by a 15 V shunt regulator with shunt current limited to 25 mA and bypassed with at least 0.01 µF ceramic. |+| 16 | SHUTDOWN | input | Protection input; when driven above 1 V, AOUT and BOUT are forced low. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-16-300mil |+| Category | Power Management (PMIC) |+| Pins | 16 |++## CAD (KiCad official)++- Symbol: `UCC3806DWTR`+- Footprint: `Package_SO:SOIC-16_3.9x9.9mm_P1.27mm`+- 3D model: SOIC-16-300mil (KiCad packages3D, STEP)+- 3D model files: `ucc3806dwtr-etched.step` / `ucc3806dwtr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ucc3806dwtr.step` / `ucc3806dwtr.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/ucc2806) (36 pp, sha256 `20f40789e136b23c`, retrieved 2026-10-07, tier: lcsc)+- **Extractor:** parts-factory `2.0.0` / `extract_pins 0.3`, primary `claude-haiku-5-5` (text), consensus `claude-sonnet-5-5` (agreed), guards: pin_guards 0.1: passed.
