# TPS22918TDBVTQ1

**Texas Instruments** · Power Distribution Switches · SOT-23-6

TPS22918TDBVTQ1 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 | VIN | power_in | Input voltage from 1V to 5.5V with required ceramic bypass capacitor to GND. |
| 2 | GND | power_in | Device ground. |
| 3 | ON | input | Active high switch control input; do not leave floating; high threshold 1V to 5.5V, low threshold 0V to 0.5V. |
| 4 | CT | output | Switch slew rate control pin that determines turn-on time through external RC network and can be left floating. |
| 5 | QOD | output | Quick Output Discharge pin that can be configured with external resistor between VOUT and QOD, tied directly to VOUT with internal resistor, or disabled by leaving pin disconnected. |
| 6 | VOUT | output | Switch output carrying load current with maximum continuous rating of 2A at TA=70°C or 1.5A at TA=85°C. |
