Overview
NEW PRODUCT AH9246 ULTRA HIGH SENSITIVITY MICROPOWER OMNIPOLAR HALL-EFFECT SWITCH Description Pin Assignments The AH9246 is an ultra high 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 AH9246 is available in industry standard TO92S and SC59 packages.
