# SY6288AAAC

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

SY6288AAAC 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 | Switch output pin; the datasheet states that OUT can be forced higher than IN at shutdown (reverse blocking, no body diode), that it is automatically discharged at shutdown (RDIS 10 Ω typ.), and that a low-ESR 150 µF aluminum electrolytic or tantalum capacitor between VOUT and GND is strongly recommended. |
| 2 | GND | power_in | Ground pin for the device. |
| 3 | OCB | output | Open-drain fault flag output that signals over current and fault conditions; the datasheet gives an OCB low resistance of 10 Ω (typ.) and an OCB delay time of 10 ms (typ.). |
| 4 | EN | input | ON/OFF control that must not float; for the SY6288A (this MPN) it is active-high, with VIL max 0.8 V and VIH min 2 V over VIN = 2.5 V to 5.5 V. |
| 5 | IN | power_in | Input supply pin, specified for 2.5 V to 5.5 V operation, with an IN UVLO threshold of 2.4 V (0.1 V hysteresis). |

## CAD (KiCad official)

- Symbol: `SY6288AAAC`
- Footprint: `Package_TO_SOT_SMD:SOT-23-5`
- 3D model: SOT-23-5 (KiCad packages3D, STEP)
- 3D model files: `sy6288aaac-etched.step` / `sy6288aaac-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `sy6288aaac.step` / `sy6288aaac.glb` are the bare package body.
