TPS2551DBVR 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 | IN | power_in | Input voltage for the power switch; connect a 0.1 μF or greater ceramic capacitor from IN to GND as close to the IC as possible. |
| 2 | GND | power_in | Ground connection, which the datasheet says should be connected externally to the PowerPAD (the DBV package has no PowerPAD pad). |
| 3 | EN | input | Enable input for the TPS2551 (active high); logic high turns on the power switch. |
| 4 | FAULT | output | Active-low open-drain output, asserted during overcurrent, overtemperature, or reverse-voltage conditions. |
| 5 | ILIM | input | External resistor sets the current-limit threshold; recommended 14.3 kΩ ≤ RILIM ≤ 80.6 kΩ. |
| 6 | OUT | output | Power-switch output. |
