MX5050L from Wuxi Maxinmicro, in a SOT-23-6L. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VS | power_in | Main supply pin for all internal biasing and gate drive charge pump auxiliary supply; operating voltage range 5-40V |
| 2 | GND | power_in | Ground return for the controller |
| 3 | OFF | input | Logic control input; high state pulls GATE pin low to turn off external MOSFET; maximum operating voltage 5.5V; 5µA typical internal pulldown |
| 4 | IN | input | Voltage sense input connected to external MOSFET source pin for forward/reverse operation detection; operating voltage range 1-40V |
| 5 | GATE | output | Gate drive output connected to external MOSFET gate; provides up to 2A peak sink current; 260ns discharge time typical for 47nF gate capacitance |
| 6 | OUT | input | Voltage sense input connected to external MOSFET drain pin for forward/reverse operation detection; operating voltage range 1-40V |
