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. |
