AP2191MPG-13

Diodes Incorporated · Power Distribution Switches · MSOP-8-EP

AP2191MPG-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 for the device.
2 IN power_in Voltage input pin; all IN pins must be tied together externally.
3 IN power_in Voltage input pin; all IN pins must be tied together externally.
4 EN input Enable input, active high on the AP2191 (active low on the AP2181).
5 FLG output Over-current and over-temperature fault report; open-drain output that goes active low when triggered.
6 OUT power_out Voltage output pin; all OUT pins must be tied together externally.
7 OUT power_out Voltage output pin; 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).
