A3212LLHLT Overview
In order to protect the magnetic switch from damage, it is packaged in the Tape & Reel (TR) enclosure. In order to ensure safety, magnetic switches are packaged in SOT-23W packages. As a maximum current, the magnetic switches can supply 2mA. It is recommended that magnetic switches should have a maximum output current of 1mA. It contains 3 terminations. If it works properly, this switch should produce a voltage of 3.5V. For reliable performance, this switch normally supplies 2.75V voltage. It is possible for this magnetic switch to supply 2.5V voltage as its minimum voltage.
