Low Power Hall Switch TLE 4913 Features Micro power design 2.4 V to 5.5 V battery operation High sensitivity and high stability of the magnetic switching points High resistance to mechanical stress Digital output signal SC59-3-x Switching for both poles of a magnet (omnipolar) Functional Description The TLE4913 is an Integrated Hall-Effect Sensor designed specifically to meet the requirements of low-power devices. e.g. as an On/Off switch in Cellular Flip-Phones, with battery operating voltages of 2.4V 5.5V. Precise magnetic switching points and high temperature stability are achieved through the unique design of the internal circuit. An onboard clock scheme is used to reduce the average operating current of the IC. During the operate phase the IC compares the actual magnetic field detected with the internally compensated switching points. The output Q is switched at the end of each operating phase. During the Stand-by phase the output stage is latched and the current consumption of the device reduced to some A. The IC switching behaviour is Omnipolar, i.e. it can be switched on with either the North or South pole of a magnet.
