MEDIUM SENSITIVITY MICROPOWER
OMNIPOLAR HALL-EFFECT SWITCH
Description
Pin Assignments
The AH9251 is a medium sensitivity Hall-effect switch with internal
pull-up resistor on the output, designed for battery operated handheld
equipments to industrial applications.
A chopper stabilized architecture improves stability of magnetic switch
points over the whole operating range. A sleep-awake logic controls
the sleep and awake time to reduce the average operating current of
the device. During the awake time, the output is changed with the
magnetic flux density. During the sleep time, the output is latched in
its previous state and the current consumption reduces to 4µA typical
at 3V. The average current consumption is 8µA at 3V.
The output can be switched on with either north or south pole of
sufficient strength. If the magnetic flux density perpendicular to the
part marking surface is larger than operating point (BOP), the output
will be turned on; if it is less than releasing point (BRP), the output will
be turned off.
The AH9251 is available in industry standard TO92S and SC59
packages.
