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; voltage above 350 mV latches device and requires power cycle restart, below 350 mV allows automatic retry after overcurrent condition. |+| 2 | VREF | power_out | Trimmed 5.1 V ±1% reference output with maximum 5 mA available current; must be bypassed to GND with 0.1 μF minimum ceramic capacitor. |+| 3 | CS-- | input | Inverting input of 3× differential current sense amplifier for pulse-by-pulse current limiting. |+| 4 | CS+ | input | Non-inverting input of 3× differential current sense amplifier for pulse-by-pulse current limiting. |+| 5 | NI | input | Non-inverting input of the error amplifier for voltage feedback control. |+| 6 | INV | input | Inverting input of the error amplifier for voltage feedback control. |+| 7 | COMP | output | 2 MHz error amplifier output and PWM comparator input with low output impedance; internally current limited to allow sinking or sourcing current and forcing COMP to GND commands zero duty cycle. |+| 8 | CT | passive | Oscillator timing capacitor connection point charged by current set at RT and discharged to GND through 2.5 mA current sink to initiate next switching cycle. |+| 9 | RT | passive | Oscillator timing resistor connection point with nominally 1.25 V potential; current mirror is limited to maximum 100 μA requiring RT greater than 12.5 kΩ. |+| 10 | SYNC | bidirectional | Bidirectional TTL-compatible pin for external synchronization; outputs oscillator pulses during dead time when free-running, or accepts external clock input when RT forced above 4.4 V; forces outputs low when SYNC high above 2 V. |+| 11 | AOUT | output | High-current gate drive output providing ±200 mA continuous and ±500 mA peak for external MOSFETs; includes inherent anti-parallel body diodes to clamp voltage swings without external clamp diodes. |+| 12 | GND | power_in | Reference ground and power ground for all device functions; bypass and timing capacitors must be connected as close as possible to this pin. |+| 13 | VC | power_in | Power supply input for FET drive outputs with input range 2.5 V to 15 V; must be capacitively bypassed for proper operation. |+| 14 | BOUT | output | High-current gate drive output providing ±200 mA continuous and ±500 mA peak for external MOSFETs; alternates with AOUT and includes inherent anti-parallel body diodes to clamp voltage swings. |+| 15 | VIN | power_in | Power supply input with 8 V to 15 V range internally regulated by 15 V shunt regulator with 25 mA maximum supply current; must be bypassed to GND with 0.01 μF minimum ceramic capacitor. |+| 16 | SHUTDOWN | input | Enhanced protection input that forces AOUT and BOUT low when driven above 1 V threshold (nominal 1.0 V for UCC2806) with 75-150 ns delay to output. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-16-300mil |+| Category | Power Management (PMIC) |+| Pins | 16 |++## CAD (KiCad official)++- Symbol: `UCC2806DW`+- Footprint: `Package_SO:SOIC-16_3.9x9.9mm_P1.27mm`+- 3D model: SOIC-16-300mil (KiCad packages3D, STEP)+- 3D model files: `ucc2806dw-etched.step` / `ucc2806dw-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ucc2806dw.step` / `ucc2806dw.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-4-5-20251001` (text), consensus `claude-sonnet-5-5` (agreed), guards: pin_guards 0.1: passed.
