Separate OUTH and OUTL pins let a resistor set the turn-on and turn-off speeds independently, and the inputs are TTL/CMOS compatible with hysteresis and an inverting option (IN-, IN+). Propagation delay is about 13 ns. A small, fast low-side driver for switch-mode supplies and motor stages.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | VDD | power_in | Bias supply input. Operating range 4.5 V to 18 V. Internal UVLO holds outputs low outside operating range. |+| 2 | OUTH | output | Sourcing current output of driver (4-A peak source). Connect a resistor between OUTH and the gate of the power-switching device to adjust turn-on speed. |+| 3 | OUTL | output | Sinking current output of driver (8-A peak sink). Connect a resistor between OUTL and the gate of the power-switching device to adjust turn-off speed. Low pulldown impedance ~0.375 Ω. |+| 4 | GND | power_in | Ground reference. All signals referenced to this pin. |+| 5 | IN- | input | Inverting input. When the driver is used in noninverting configuration, connect IN- to GND to enable the output. Output is held LOW if IN- is unbiased or floating (internal pullup/pulldown). |+| 6 | IN+ | input | Noninverting input. When the driver is used in inverting configuration, connect IN+ to VDD to enable the output. Output is held LOW if IN+ is unbiased or floating (internal pullup/pulldown). |++## Key specifications++| Parameter | Value |+|---|---|+| Type | Single low-side gate driver |+| Peak source | 4 A |+| Peak sink | 8 A |+| Outputs | Split OUTH / OUTL (independent R) |+| Inputs | TTL/CMOS, dual (IN+, IN-) |+| Propagation delay | ~13 ns |+| Supply | 4.5-18 V |+| Package | SOT-23-6 |++## Ordering variants++- `UCC27511DBVR (SOT-23-6, tape & reel)`+- `UCC27511ADBVR (SOT-23-6, variant)`++## CAD (KiCad official)++- Symbol: `Driver_FET:UCC27511ADBV (KiCad official)`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6 (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/ucc27511.pdf) (40 pp, sha256 `781cc451dbb371a4`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
