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.
