LM5050MK-1 from Texas Instruments, in a TSOT-23-6. 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 | Supply pin for internal biasing and gate drive charge pump with operating range 5V to 75V. |
| 2 | GND | power_in | Ground return for the controller. |
| 3 | OFF | input | Logic input to turn off external MOSFET when high; operating range 0V to 5.5V. |
| 4 | IN | input | Voltage sense connection to external MOSFET source pin with operating range 5V to 75V. |
| 5 | GATE | output | Gate drive output connected to external MOSFET gate; clamped to 12V above IN pin. |
| 6 | OUT | output | Voltage sense connection to external MOSFET drain pin with operating range 5V to 75V. |
