**MONOLITHIC POWER SYSTEMS** · Global Sourcing Parts · SOIC-8

MP62341DS-LF-Z from MONOLITHIC POWER SYSTEMS, 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 | GND | power_in | Ground reference for the device; the SOIC8 package has no exposed pad. |
| 2 | IN | power_in | Input voltage pin that accepts 2.7V to 5.5V input. |
| 3 | EN1 | input | Enable input for channel 1, active high on the MP62341 (logic high min 2V, logic low max 0.8V). |
| 4 | EN2 | input | Enable input for channel 2, active high on the MP62341 (logic high min 2V, logic low max 0.8V). |
| 5 | FLAG2 | output | Open-drain, active-low over-current flag output for the IN-to-OUT2 switch, with 8ms typical deglitch. |
| 6 | OUT2 | power_out | IN-to-OUT2 power-distribution switch output, current-limited (1A max continuous load). |
| 7 | OUT1 | power_out | IN-to-OUT1 power-distribution switch output, current-limited (1A max continuous load). |
| 8 | FLAG1 | output | Open-drain, active-low over-current flag output for the IN-to-OUT1 switch, with 8ms typical deglitch. |
