A3422LKA-T Overview
An integrated magnetic switch is packaged within the Bulk in order to protect it against damage. Safety precautions are taken by packaging the magnetic switches in 5-SSIP packages. A good performance can be achieved with magnetic switches that can deliver 18mA as the maximum current. When these switches are working, 30mA is the maximum current they can output. Switches have 5 pins for operation. As far as terminations are concerned, there are 5. As a general rule, the switches should output 30mA.
