AP2146SG-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 (active high on AP2156), with VIL max 0.8V and VIH min 2V. |
| 2 | FLG1 | tri_state | Switch 1 over-current and over-temperature fault report, open-drain output that goes low after a 7ms typical deglitch. |
| 3 | FLG2 | tri_state | Switch 2 over-current and over-temperature fault report, open-drain output that goes low after a 7ms typical deglitch. |
| 4 | EN2 | input | Switch 2 enable input, active low on AP2146 (active high on AP2156), with VIL max 0.8V and VIH min 2V. |
| 5 | OUT2 | power_out | Switch 2 voltage output pin, current limited to 0.8A typical with 0.5A recommended maximum continuous load. |
| 6 | GND | power_in | Ground. |
| 7 | IN | power_in | Voltage input pin, operating range 2.7V to 5.5V, shared by both switches. |
| 8 | OUT1 | power_out | Switch 1 voltage output pin, current limited to 0.8A typical with 0.5A recommended maximum continuous load. |
