The TLE4916-1K is an integrated Hall-Effect Sensor designed specifically to meet the requirements of low-power
applications with operating voltages of 2.4V - 5.0V.
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 operating phase the IC compares the actual magnetic field detected to 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 4µA
µA (typ. value).
The IC switching behaviour is designed as a latch, i.e. it can be switched on (Q = LO) with the south pole of a
magnet and switched off (Q = HI) with the north pole.
