# AP2156SG-13

**Diodes Incorporated** · Power Distribution Switches · SOIC-8

AP2156SG-13 from Diodes Incorporated, in a SOIC-8. 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 | EN1 | input | Switch 1 enable input, active low on AP2146 or active high on AP2156, with VIL max 0.8 V and VIH min 2 V. |
| 2 | FLG1 | output | Switch 1 over-current and over-temperature fault report, open-drain output that goes active low after a nominal 7 ms deglitch. |
| 3 | FLG2 | output | Switch 2 over-current and over-temperature fault report, open-drain output that goes active low after a nominal 7 ms deglitch. |
| 4 | EN2 | input | Switch 2 enable input, active low on AP2146 or active high on AP2156, with VIL max 0.8 V and VIH min 2 V. |
| 5 | OUT2 | power_out | Switch 2 voltage output; the absolute maximum output voltage is VIN + 0.3 V. |
| 6 | GND | power_in | Ground reference pin for the device. |
| 7 | IN | power_in | Voltage input pin, recommended 2.7 V to 5.5 V with an absolute maximum of 6.5 V. |
| 8 | OUT1 | power_out | Switch 1 voltage output; the absolute maximum output voltage is VIN + 0.3 V. |
