# SGM2576YN5G

**SGMICRO** · Power Distribution Switches · SOT-23-5

SGM2576YN5G 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 through the integrated 100mΩ (TYP at VIN = 5V, 500mA) N-MOSFET; on the SGM2576 it discharges through 50Ω (RDIS) when the switch is off. |
| 2 | GND | power_in | Ground reference pin; the RILIM current-limit resistor is connected between the ILIM pin and this pin. |
| 3 | ILIM | input | Current limit programming pin: connect a resistor RILIM from this pin to GND, with ILIM = 6800/RILIM (A), giving a limit programmable from 0.1A to 2.5A. |
| 4 | EN | input | Chip enable, logic high enables the device; VIH is 1.6V min and VIL is 0.4V max, with an integrated 500kΩ pull-down, and the EN voltage range is -0.3V to 5.5V. |
| 5 | VIN | power_in | Switch input supply, operating over 2.5V to 5.5V, with the device's under-voltage lockout protecting the input. |
