A3211ELHLT-T Overview
Designed to protect magnetic switches from damage, the Tape & Reel (TR) package contains the switches. Safety precautions are taken by packaging the magnetic switches in SOT-23W packages. In operation, these switches can output a maximum current of 1mA. There is a maximum current that these switches can supply of 1μA. There are 3 pins on the switches that allow them to work. As far as terminations are concerned, there are 3. There should be 1mA current output from the switches in general. This switch will normally supply 2.75V voltage for reliable operation. The minimum voltage supplied by this magnetic switch can be 2.5V. It is possible for the magnetic switches to supply a voltage of 2.75V when they are operating.
