SGM2588CYN5G from SGMICRO, 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 | Switch output pin, driven from VIN through the integrated 100mΩ (typ) N-MOSFET, and the output discharges through about 50Ω when the switch is off on SGM2588C. |
| 2 | GND | power_in | Ground reference pin for the device. |
| 3 | nFAULT | output | Active-low open-drain fault flag that asserts for over-current or thermal shutdown, and over-current must last longer than tD (13ms typ) before nFAULT asserts. |
| 4 | EN | input | Active-high chip enable for SGM2588C that must not be left floating; this variant has no internal pull-down resistor, which is provided only on SGM2588G/I/K. |
| 5 | VIN | power_in | Switch input pin, operating over a 2.5V to 5.5V input voltage range. |
