DIO7553ST6 from DIOO, 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 (2.7V to 5.5V operating range); connect a 0.1µF or greater ceramic capacitor from IN to GND as close to the IC as possible. |
| 2 | GND | power_in | Ground pin. |
| 3 | EN | input | Enable input for the DIO7553, active high: logic high turns on the power switch (VIH min 1.4V, VIL max 0.4V). |
| 4 | FAULT | output | Active-low open-drain output, asserted during over current, over temperature, or reverse-voltage conditions (max 6.0V, 10mA flag current). |
| 5 | ILIM | passive | External resistor to GND sets the current-limit threshold; recommended 10kΩ ≤ RILIM ≤ 64kΩ, IOS(A)=25752/Rset(Ω). |
| 6 | OUT | power_out | Power-switch output. |
