# TPS22965QWDSGTQ1

**Texas Instruments** · Power Distribution Switches · WSON-8-EP(2x2)

TPS22965QWDSGTQ1 from Texas Instruments, in a WSON-8-EP(2x2). 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 | Switch input; input bypass capacitor recommended to minimize VIN dip, and it must be connected to both pin 1 and pin 2 (VIN range 0.8 V to VBIAS). |
| 2 | VIN | power_in | Switch input, internally the same net as pin 1 and must be connected to pin 1 (VIN range 0.8 V to VBIAS). |
| 3 | ON | input | Active-high switch control input that must not be left floating; VIH min 1.2 V and VIL max 0.5 V for VBIAS = 2.5 V to 5.5 V. |
| 4 | VBIAS | power_in | Bias supply to the device with a recommended range of 2 V to 5.5 V. |
| 5 | GND | power_in | Device ground. |
| 6 | CT | output | Switch slew-rate (VOUT rise time) control pin that can be left floating. |
| 7 | VOUT | power_out | Switch output, up to 4 A maximum continuous switch current. |
| 8 | VOUT | power_out | Switch output, same net as pin 7, up to 4 A maximum continuous switch current. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
