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 | IN | power_in | Switch input. Load switch source supply, 1.6 V to 5.5 V (abs max 6 V). Bypass with a ceramic capacitor close to the pin. |+| 2 | GND | power_in | Device ground reference. |+| 3 | ON | input | Active-high switch enable control input. VIH ≥ 1 V, VIL ≤ 0.35 V, abs max 6 V. Contains a smart pull-down (~530 kΩ) that keeps ON low until deliberately driven high; do not leave floating in normal operation. |+| 4 | NC | unconnected | No connect. Leave floating. |+| 5 | QOD | output | Quick Output Discharge pin. Internal ~24 Ω discharge path to GND when the switch is off. Tie directly to VOUT to use the internal RPD, add an external resistor between VOUT and QOD to adjust fall time, or leave floating to disable QOD. Abs max 6 V. |+| 6 | VOUT | power_out | Switch output. Connected to IN through the internal N-channel MOSFET (RON ≈ 90 mΩ at 3.6 V) when ON is high. Supports up to 1.5 A continuous with controlled slew-rate turn-on. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SC-70-6 |+| Category | PMIC |+| Pins | 6 |++## Ordering variants++- `TPS22919DCKRDCKR`+- `TPS22919DCKRDCKT`++## CAD (KiCad official)++- Symbol: `TPS22919DCKR`+- Footprint: `Package_TO_SOT_SMD:SOT-363_SC-70-6`+- 3D model: SC-70-6 (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/tps22919.pdf) (27 pp, sha256 `743c59b01fb0891d`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
