SGM2554AYN5G

SGMICRO · Power Distribution Switches · SOT-23-5

SGM2554AYN5G 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; SGM2554A SOT-23-5 pin 1 is tied to VOUT, which is also pin 5, and the switch RDS(ON) is 95mΩ typical and 150mΩ maximum at IL = 1A.
2 GND power_in Ground reference pin for the device.
3 VIN power_in Switch input; input voltage range is 2.2V to 5.5V, with UVLO threshold 1.65V rising and 50mV hysteresis.
4 EN input Chip enable pin on the SGM2554A; logic high enables the device, with VIH of 1.5V minimum and VIL of 0.4V maximum, and absolute maximum rating of -0.3V to 6V.
5 VOUT power_out Switch output; pin 5 is internally connected to VOUT together with pin 1.
