SGM2588CYN5G

SGMICRO · Power Distribution Switches · SOT-23-5

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.
