AH9249

HIGH SENSITIVITY MICROPOWER OMNIPOLAR HALL-EFFECT SWITCH

The AH9249 is an ultra-sensitive Hall-effect switch with digital latched output, mainly designed for battery-operation, hand-held equipments.

Special CMOS process is used for low-voltage and low-power requirement. A chopper stabilized amplifier improves stability of magnetic switch points. A sleep-awake logic controls the IC in sleep time or awake time. This function will reduce the average operating current of the IC. 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 will reduce to some uA.

The IC switching behaviour is omnipolar, either north or south pole sufficient strength will turn the output on. If the magnetic flux density 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 AH9249 is available in TO-92S-3, SOT-23-3 and DFN-2x2-3 packages which are optimized for most applications.
