TPS22918DBVR from Texas Instruments, in a SOT-23-6. 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 | VIN | power_in | Switch input. Input voltage range 1 V to 5.5 V (absolute max 6 V). Place ceramic bypass capacitor(s) (≥1 µF recommended) between this pin and GND. |
| 2 | GND | power_in | Device ground. Common return for input, output, and control. |
| 3 | ON | input | Active-high switch enable control input. VIH ≥ 1 V, VIL ≤ 0.5 V (over VIN = 1 V to 5.5 V). Do not leave floating. Interfaces directly with low-voltage control signals (≥1 V GPIO). |
| 4 | CT | passive | Switch slew-rate (rise-time) control pin. Connect an external capacitor to GND to configure the output rise time, or leave floating to use the default rise time. |
| 5 | QOD | passive | Quick Output Discharge pin. Enable by placing an external resistor between VOUT and QOD, tie directly to VOUT to use the internal pull-down resistor (RPD ≈ 25 Ω at VIN = 3.3 V), or leave floating to disable QOD. |
| 6 | VOUT | power_out | Switch output. Delivers the switched VIN rail to the load (up to 2 A continuous). RON typically 52 mΩ at VIN = 5 V, 53 mΩ at VIN = 3.3 V. |
