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.

Notes:
4. Stresses greater than the 'Absolute Maximum Ratings' specified above may cause permanent damage to the device. These are stress ratings only;
functional operation of the device at these or any other conditions exceeding those indicated in this specification is not implied. Device reliability may be
affected by exposure to absolute maximum rating conditions for extended periods of time.
5. The absolute maximum VDD of 7V is a transient stress rating and is not meant as a functional operating condition. It is not recommended to operate the
device at the absolute maximum rated conditions for any period of time.
6. Electronic semiconductor products are sensitive to Electro Static Discharge (ESD). Always observe Electro Static Discharge control procedures
whenever handling semiconductor products.
