A3214ELHLT-T Overview
A protective Tape & Reel (TR) package is used to protect the magnetic switch against damage. For safety reasons, the magnetic switches are packaged in SOT-23W packages. The maximum current that can be produced by these switches is 1mA. They can supply up to 22μA amps of current. Switches are operated by 3 pins. This document has 3 terminations. It is generally recommended that the switches output 1mA current. If this switch is functioning properly, it should supply a voltage of 5.5V. For reliable operation, this switch supplies 3V voltage. A magnetic switch can supply a voltage as low as 2.4V. During operation, the magnetic switches could supply 3V.
