SGM2553YN6G

SGMICRO · Power Distribution Switches · SOT-23-6

SGM2553YN6G from SGMICRO, 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; connect a 0.1µF or greater ceramic capacitor from IN to GND as close to the IC as possible.
2 GND power_in Ground; the datasheet specifies connecting it externally to the exposed pad.
3 EN input Enable input; logic high turns on the power switch, with VIH of 1.4V minimum and VIL of 0.3V maximum.
4 FAULT output Active-low open-drain output asserted during over-current, over-temperature, or reverse-voltage conditions; continuous FAULT sink current is limited to 25mA absolute maximum and 0 to 10mA recommended.
5 ILIM passive External resistor sets the current limit threshold; recommended 20kΩ ≤ RILIM ≤ 387kΩ.
6 OUT power_out Power switch output; continuous output current range is 0A to 1.5A.
