LM5068MM-2 from Texas Instruments, in a VSSOP-8-0.65mm. 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 | PWRGD | output | Open-drain power-good indicator that is active HIGH on the LM5068-2 after a successful power-up sequence, and input over- or under-voltage faults cancel it. |
| 2 | OV | input | Line over-voltage shutdown input, where an external divider sets the shutdown level against a 2.5V threshold (2.45V to 2.55V) and a 20µA hysteresis current is sourced into the divider when the pin exceeds 2.5V. |
| 3 | UV | input | Line under-voltage shutdown input, where an external divider sets the shutdown level against a 2.5V threshold (2.45V to 2.55V) and a 20µA hysteresis current is sunk from the divider when the pin falls below 2.5V. |
| 4 | VEE | power_in | Negative supply voltage input, with the operating supply range VDD − VEE of 10V to 90V. |
| 5 | SENSE | input | Current sense input across the external sense resistor Rs, where the fault timer starts above 50mV, load current is limited to 100mV/Rs, and the fast gate pull-down engages above 200mV; the absolute maximum is 8V to VEE. |
| 6 | GATE | output | N-channel MOSFET gate drive output, pulled high by a 60µA current source to turn on the external MOSFET. |
| 7 | TIMER | passive | External capacitor pin that sets the initial start-up delay and the over-current shutdown delay, and also sets the automatic re-try timing after a fault on the -2 version. |
| 8 | VDD | power_in | Positive supply voltage input, with an absolute maximum of 100V to VEE and an operating range of 10V to 90V. |
