It connects VIN to VOUT under an active-high ON control, from a 1 to 5.5 V rail at up to 2 A, with a low on-resistance. An external capacitor on CT sets the output slew rate to tame inrush, and QOD gives a controlled quick output discharge when the switch turns off. The clean way to sequence and hot-swap power rails to sub-circuits.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | VIN | power_in | Switch input, 1 V to 5.5 V. Place ceramic bypass capacitor(s) (>=1 uF recommended) between this pin and GND. Absolute max 6 V. |+| 2 | GND | power_in | Device ground reference. |+| 3 | ON | input | Active-high switch control input. VIH >= 1 V, VIL <= 0.5 V (VIN = 1 to 5.5 V). Low-voltage compatible (1 V or higher GPIO). Do not leave floating. |+| 4 | CT | passive | Switch slew-rate (rise-time) control. Connect an external capacitor to GND to program the rise time; may be left floating for the default rise time. |+| 5 | QOD | passive | Quick Output Discharge pin. Configure by placing an external resistor between VOUT and QOD, tying QOD directly to VOUT to use the internal pull-down (RPD ~24-45 Ohm depending on VIN), or leaving floating to disable QOD. |+| 6 | VOUT | power_out | Switch output. Connected to VIN through the internal N-channel MOSFET (RON ~52 mOhm typ at VIN = 5 V; 53 mOhm typ at VIN = 3.3 V). Supports up to 2 A continuous. |++## Key specifications++| Parameter | Value |+|---|---|+| Type | Single-channel load switch (integrated N-FET) |+| Input voltage | 1-5.5 V |+| Output current | up to 2 A |+| Control | ON (active-high) |+| Slew-rate control | CT pin (external cap sets rise time) |+| Output discharge | QOD (quick output discharge) |+| Package | SOT-23-6 |+| Body (L×W×H) | 2.9 × 1.6 × 1.1 mm |++## Ordering variants++- `TPS22918DBVR (SOT-23-6, tape & reel)`++## CAD (KiCad official)++- Symbol: `TPS22918 (Adom-authored grouped symbol via adom-symbol; not in KiCad libs)`+- Footprint: `Package_TO_SOT_SMD:SOT-23-6`+- 3D model: SOT-23-6 (KiCad packages3D)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/tps22918.pdf) (30 pp, sha256 `1b28eb58003d28b1`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude) — every pin and dimension is cited to a datasheet page; refuses to fabricate.+- **CAD:** KiCad official libraries (CC-BY-SA 4.0).++[Datasheet PDF](docs/tps22918-datasheet.pdf)
