Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | AIN | input | Isolated analog sensing input (referenced to COM). Parallel a small capacitor to COM for better noise immunity. Recommended operating input range is 0.6 V to 4.5 V referenced to COM. Tie to COM if unused. |+| 2 | OC | input | Over-current detection input (referenced to COM). Supports lower-threshold detection for SenseFET, DESAT, and shunt-resistor sensing. Tie to COM if unused. |+| 3 | COM | power_in | Common ground reference on the secondary (gate-drive) side. Connect to the emitter of the IGBT or the source of the SiC-MOSFET being driven. |+| 4 | OUTH | output | Gate driver output, pull-up (source) path. Delivers up to 10-A peak source current to the power-transistor gate. Swings between VDD and COM. |+| 5 | VDD | power_in | Positive supply rail for gate-drive voltage (13 V to 33 V VDD-COM recommended, 36 V max VDD-VEE). Bypass with a >10-uF capacitor to COM close to the pin to support specified source peak current. |+| 6 | OUTL | output | Gate driver output, pull-down (sink) path. Sinks up to 10-A peak current from the power-transistor gate. Swings between VDD and VEE. |+| 7 | CLMPI | input | Internal Active Miller Clamp input. Connect this pin directly to the gate of the power transistor to enable the internal 4-A Miller clamp when the gate falls below the clamp threshold. Leave floating or tie to VEE if unused. |+| 8 | VEE | power_in | Negative supply rail for gate-drive voltage (down to -17.5 V VEE-COM abs max). Bypass with a >10-uF capacitor to COM close to the pin to support specified sink peak current. |+| 9 | GND | power_in | Input-side (primary) power supply and logic ground reference. |+| 10 | IN+ | input | Non-inverting gate driver control (PWM) input, referenced to GND. Logic thresholds 0.7xVCC (VIH) / 0.3xVCC (VIL). Tie to VCC if unused. |+| 11 | IN- | input | Inverting gate driver control (PWM) input, referenced to GND. Logic thresholds 0.7xVCC (VIH) / 0.3xVCC (VIL). Tie to GND if unused. |+| 12 | RDY | output | Power-good indicator for VCC-GND and VDD-COM UVLO status. Open-drain output; can be paralleled with other RDY signals. Requires an external pull-up to VCC. |+| 13 | FLT | output | Active-low fault alarm output asserted upon over-current or short-circuit detection. Open-drain output; can be paralleled with other faults. Requires an external pull-up to VCC. |+| 14 | RST/EN | input | Dual-purpose reset/enable input. (1) Enable/shutdown of the output side: turning off pulls the FET off via a normal turn-off. (2) Resets a latched DESAT/FLT fault when held low for >1000 ns; FLT is deasserted on the rising edge of RST/EN. In automatic-reset mode, functions purely as EN. Referenced to GND with 0.7xVCC/0.3xVCC logic thresholds. |+| 15 | VCC | power_in | Input-side (primary) logic power supply, 3.0 V to 5.5 V (6 V abs max). Bypass with a >1-uF capacitor to GND close to the pin. |+| 16 | APWM | output | Isolated Analog Sensing PWM output on the primary (input) side. Reproduces the isolated analog signal from AIN as a PWM duty cycle referenced to GND. Leave floating if unused. Max output current 20 mA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-16-300mil |+| Category | Power Management (PMIC) |+| Pins | 16 |++## Ordering variants++Same part, different packaging or reel option.++- `UCC21710QDWRQ1`++## CAD (KiCad official)++- Symbol: `UCC21710QDWRQ1`+- Footprint: `Package_SO:SOIC-16_3.9x9.9mm_P1.27mm`+- 3D model: SOIC-16-300mil (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/ucc21710-q1) (61 pp, sha256 `a6b1641a6f247e51`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
