A1223LLHLX-T Overview
Tape & Reel (TR) package done to protect the magnetic switch from damage. SOT-23W packages are used for safety reasons to protect magnetic switches. The magnetic switches can supply 4mA as the maximum current for good performance. The maximum current these switches can supply when they work is 25mA. For the switches to function, there are 3 pins. The current output of the switches should, in general, be 25mA.
