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 | ENA | input | Enable input for Channel A. Biasing ENA LOW disables Channel A output regardless of INA state; pulling ENA HIGH enables Channel A output. If floating, Channel A is enabled by default via an internal ~200 kΩ pullup resistor. Recommended to tie to VDD if unused. Threshold: VENx_H=2V typ, VENx_L=1V typ, hysteresis ~1V. |+| 2 | INA | input | Non-inverting input to Channel A. OUTA is held LOW if INA is unbiased or floating due to an internal ~120 kΩ pulldown resistor. Connect to GND if unused. Input high threshold VINx_H=2V typ, low threshold VINx_L=1V typ, capable of handling -10V. |+| 3 | GND | power_in | Device ground. All signals are referenced to this pin. |+| 4 | INB | input | Non-inverting input to Channel B. OUTB is held LOW if INB is unbiased or floating due to an internal ~120 kΩ pulldown resistor. Connect to GND if unused. Same thresholds as INA (VINx_H=2V typ, VINx_L=1V typ), capable of handling -10V. |+| 5 | OUTB | output | Channel B gate driver output. 5A peak source/sink current, low-side push-pull output. Pullup RoH=5Ω typ (PMOS DC), pulldown RoL=0.6Ω typ. Output swings from GND to VDD. |+| 6 | VDD | power_in | Bias supply input. Recommended operating range 4.5V to 26V (absolute max 30V). UVLO rising ~4.1V, falling ~3.8V, 0.3V hysteresis. Bypass with two ceramic capacitors (typically ≥1 µF and 0.1 µF) referenced to GND. |+| 7 | OUTA | output | Channel A gate driver output. 5A peak source/sink current, low-side push-pull output. Pullup RoH=5Ω typ (PMOS DC), pulldown RoL=0.6Ω typ. Output swings from GND to VDD. |+| 8 | ENB | input | Enable input for Channel B. Biasing ENB LOW disables Channel B output regardless of INB state; pulling ENB HIGH enables Channel B output. If floating, Channel B is enabled by default via an internal ~200 kΩ pullup resistor. Recommended to tie to VDD if unused. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-8 |+| Category | PMIC |+| Pins | 8 |++## Ordering variants++- `UCC27624DRD`+- `UCC27624DRDR`+- `UCC27624DRDDA`+- `UCC27624DRDDAR`+- `UCC27624DRDGN`+- `UCC27624DRDGNR`+- `UCC27624DRDGK`+- `UCC27624DRDGKR`+- `UCC27624DRDSD`+- `UCC27624DRDSDR`++## CAD (KiCad official)++- Symbol: `UCC27624DR`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/ucc27624.pdf) (51 pp, sha256 `35fad5d99f446b96`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
