          Adjustable Over-Voltage Protection Switch
           
          Adjustable Over-Voltage Protection Switch
          GENERAL DESCRIPTION

          The SGM40659/60/61 over-voltage protection devices feature a low 27mΩ (TYP) on-resistance high current integrated MOSFET which actively protect low-voltage systems against voltage supply faults up to +28VDC.

          An input voltage exceeding the over-voltage threshold will cause the internal MOSFET to turn off, preventing excessive voltage from damaging downstream devices. When the OVLO input is connected to GND, the SGM40659/60/61 automatically choose the internal fixed OVLO threshold, preset to be typical 15.61V/6.80V/5.94V (SGM40659/60/61). The over-voltage protection threshold can be adjusted with optional external resistors to any voltage between 4V and 20V.

          In case the device temperature exceeds the maximum junction temperature, the device switches off.

          The SGM40659/60/61 are available in Green WLCSP-1.30×0.94-6B package, and operate over an ambient temperature range of -40 to +85.
