Overview
Low Power Hall Switch TLE 4917 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 • Switching for both poles of a magnet (omnipolar) • Programming pin for the switching direction of the output Functional Description The TLE 4917 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-b...
