SY6287CABC

Silergy Corp · Power Distribution Switches · SOT-23-6

SY6287CABC from Silergy Corp, 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 pin, decoupled with a 10µF capacitor to GND; the input operating range is 2.5V to 5.5V.
2 GND power_in Ground pin.
3 EN input ON/OFF control, active high; do not leave it floating.
4 OCB output Open drain fault flag output (asserted low on over-current or over-temperature fault).
5 ISET passive Current limit programming pin; connect a resistor RSET from this pin to ground, with ILIM (A) = 230/RSET (Ω).
6 OUT power_out Output pin, decoupled with a 10µF capacitor to GND.
