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 µA.
The IC switching behaviour is Omnipolar, i.e. it can be switched on with either the North or
South pole of a magnet.
