# SY6288E1AAC

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

SY6288E1AAC 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, decoupled with a 10µF capacitor to GND; the datasheet states OUT can be forced higher than IN at shutdown. |
| 2 | GND | power_in | Ground pin. |
| 3 | OCB | output | Open-drain fault flag, active low: it goes low when over-current protection or thermal shutdown occurs while the device is enabled, and is high impedance when no protection is active or the device is disabled. |
| 4 | EN/ENB | input | ON/OFF control that must not be left floating; EN is active high on the SY6288E1AAC and ENB is active low on the E2 variant, with logic-low VIL max 0.5 V and logic-high VIH min 1.0 V. |
| 5 | IN | power_in | Input pin, decoupled with a 10µF capacitor to GND; recommended operating range is 2.5 V to 5.5 V. |
