**TEXAS INSTRUMENTS** · Global Sourcing Parts · SOT-23-6

TPS22950CQDDCRQ1 from TEXAS INSTRUMENTS, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | ON | input | Active-high switch control input (VIH 1 V to 5.5 V, VIL 0 to 0.35 V) with a smart pulldown of 500 kΩ typ when low; do not leave floating. |
| 2 | VIN | power_in | Switch input supplying the load, operating range 1.8 V to 5.5 V. |
| 3 | GND | power_in | Device ground. |
| 4 | ILIM | passive | Current-limit adjust pin; a resistor to ground sets the limit per ILIM = 1.18 × RILIM^-1.072, from 0.05 A to 3.5 A typ. |
| 5 | VOUT | power_out | Switch output with reverse current blocking and 130 Ω typ quick output discharge when off, rated up to 2.7 A continuous. |
| 6 | FLT | output | Open-drain fault output that is pulled low during thermal shutdown or reverse-current conditions. |
