A3212EELLT-T Overview
The magnetic switch is packaged in the Cut Tape (CT) to prevent damage. 3-PowerXDFN packages are used for safety reasons to protect magnetic switches. A magnetic switch is capable of supplying 2mA as the maximum current for maximum performance. It is possible for these switches to operate at a maximum current of 1mA. Magnet switches should have a maximum current of 1mA in order to function correctly. There is 1μA maximum current that these switches can supply. The switches have 3 pins for working. There should be 1mA current output from the switches in general. Magnetic switches can be operated at a maximum operating temperature of 85°C. For this magnetic switch to operate, however, the operating temperature must be greater than -40°C. During operation, the magnetic switches are capable of supplying 2.75V voltage. The maximum voltage this component can supply is 3.5V. The switches are capable of supplying 2.5V as the minimum voltage.
