# TPAP22802AW5

**TECH PUBLIC** · Power Distribution Switches · SOT-23-5

TPAP22802AW5 from TECH PUBLIC, in a SOT-23-5. 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 | VOUT | power_out | Output voltage pin that follows the input voltage; when ENB is high or EN is low, the output is discharged by an internal resistor. |
| 2 | GND | power_in | Ground. |
| 3 | OCB | output | Open-drain fault indication pin that goes low when a current limit or over-temperature condition is detected after a 12ms deglitch time. |
| 4 | EN | input | Enable input: high enables the device, low disables it (VIH min 1.3V, VIL max 0.7V), and the pin cannot be left floating. |
| 5 | VIN | power_in | Power supply input connected to the external DC supply, 2.5V to 5.5V operating range. |
