TPS2553QDBVRQ1 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 | input | Input voltage; 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; connect externally to the PowerPAD circuit board traces. |
| 3 | EN | input | Enable input; logic high turns on the power switch (active-high version, as ordered for TPS2553QDBVRQ1). |
| 4 | FAULT | output | Active-low open-drain output, asserted during overcurrent, overtemperature, or reverse-voltage conditions. |
| 5 | ILIM | output | External resistor used to set the current-limit threshold; recommended 15 kΩ ≤ RILIM ≤ 232 kΩ. |
| 6 | OUT | output | Power-switch output. |
