# TPS22975NDSGR

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

TPS22975NDSGR 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, must be connected to pin 2 as well, with an input bypass capacitor recommended to minimize VIN dip; input range is 0.6 V to VBIAS. |
| 2 | VIN | power_in | Switch input, must be connected to pin 1 as well, with an input bypass capacitor recommended to minimize VIN dip; input range is 0.6 V to VBIAS. |
| 3 | ON | input | Active-high switch control input that must not be left floating, with VIH of 1.05 V to 1.2 V min depending on VBIAS and temperature and VIL max of 0.5 V. |
| 4 | VBIAS | power_in | Bias supply to the device, with a recommended voltage range of 2.5 V to 5.7 V. |
| 5 | GND | power_in | Device ground. |
| 6 | CT | output | Switch slew rate (rise time) control pin that can be left floating. |
| 7 | VOUT | power_out | Switch output, which must be connected to pin 8 as well; the TPS22975N variant has no quick output discharge. |
| 8 | VOUT | power_out | Switch output, which must be connected to pin 7 as well; the TPS22975N variant has no quick output discharge. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
