LM5068MM-2

Texas Instruments · Surge Suppressors · VSSOP-8-0.65mm

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.
