TPS25221DRVR from Texas Instruments, in a WSON-6-EP(2x2). 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 | OUT | power_out | Power switch output, connect to load |
| 2 | ILIM | output | External resistor used to set current limit threshold |
| 3 | FAULT | output | Active-low open-drain output asserted during over-current or over-temperature conditions |
| 4 | EN | input | Enable input (active high); logic high enables power switch, logic low disables part |
| 5 | GND | power_in | Ground connection |
| 6 | IN | power_in | Input voltage and power switch drain; connect 0.1 μF or greater ceramic capacitor from IN to GND close to IC |
| 7 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
