A3212LLHLT-T Overview
ldeally, the magnetic switch should be packaged in the Tape & Reel (TR) for protection against damage. As a safety precaution, the magnetic switches are packaged in SOT-23W packages. The maximum current that can be output by these switches is 1mA. This switch is capable of supplying a maximum current of 1μA. In order for the switches to function, they have 3 pins. As far as terminations are concerned, there are 3. Generally, switches should output 1mA current. When this switch is in a reliable operating state, it typically supplies 2.75V voltage. This magnetic switch can supply a voltage as low as 2.5V. When operating, the magnetic switches could supply 2.75V voltage.
