SY6288C3AAC

Silergy Corp · Power Distribution Switches · SOT-23-5

SY6288C3AAC from Silergy Corp, 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 OUT power_out Output pin of the power switch; when the chip is disabled, OUT can be forced higher than IN without reverse current flow because the device has no body diode.
2 GND power_in Ground pin.
3 OCB output Open-drain fault flag, active low, asserted on over-temperature shutdown and on over-current or reverse blocking that persists for 10 ms; OCB low resistance is 10 Ω.
4 EN input ON/OFF control, active high for SY6288C3 (do not float); VIL maximum 0.8 V and VIH minimum 2 V, with EN limited to -0.3 V to VIN+0.3 V.
5 IN power_in Input (supply) pin, operating range 2.5 V to 5.5 V; all pins have a 6 V absolute maximum rating.
