SY6288C30AAC

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

SY6288C30AAC 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; at shutdown OUT can be forced higher than IN because the P-channel FET has no body diode, and the SY6288C30 auto-discharges OUT when shut down.
2 GND power_in Ground pin; a low-ESR 150uF aluminum electrolytic or tantalum capacitor between VOUT and GND is strongly recommended.
3 OCB output Open-drain fault flag, asserted low on over-current or reverse blocking persisting for 10 ms, or on over-temperature shutdown (150 °C), with about 10 Ω low-state resistance.
4 EN input ON/OFF control, active high for the SY6288C30 (high enable); it must not float and EN/ENB input range is -0.3 V to VIN+0.3 V.
5 IN power_in Input supply pin, specified for 2.5 V to 5.5 V with a 6 V absolute maximum; a 10 uF ceramic capacitor from VIN to GND is strongly recommended.
