GENERAL DESCRIPTION
The FSH4913 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 to 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 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 behavior is Omnipolar, i.e. it can be
switched on with either the North or South pole of a
magnet.
