AP2171DMPG-13 from Diodes Incorporated, in a MSOP-8-EP. 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 | GND | power_in | Ground pin; the exposed pad must be connected to GND for thermal impedance but must not be used as the electrical ground conduction path. |
| 2 | IN | power_in | Voltage input pin, input voltage range 2.7V to 5.5V (absolute maximum 6.5V); all IN pins must be tied together externally. |
| 3 | IN | power_in | Voltage input pin, input voltage range 2.7V to 5.5V (absolute maximum 6.5V); all IN pins must be tied together externally. |
| 4 | EN | input | Enable input, active low on AP2161D and active high on AP2171D; logic low maximum 0.8V and logic high minimum 2V. |
| 5 | FLG | output | Over-current and over-temperature fault report; open-drain output that is active low when triggered, with a 7ms typical blanking time before assertion. |
| 6 | OUT | power_out | Voltage output pin, recommended maximum continuous load current 1A; all OUT pins must be tied together externally. |
| 7 | OUT | power_out | Voltage output pin, recommended maximum continuous load current 1A; all OUT pins must be tied together externally. |
| 8 | NC | unconnected | No internal connection; the datasheet recommends tying this pin to the OUT pins. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
