NOT RECOMMENDED FOR NEW DESIGN USE AH1808 AH9248 HIGH SENSITIVITY MICROPOWER OMNIPOLAR HALL-EFFECT SWITCH Description Pin Assignments The AH9248 is an ultra-sensitive Hall-effect switch with digital latched output, mainly designed for battery-operation, hand-held equipments. (Front View) 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 μA. 3 OUTPUT 2 GND 1 VCC TO-92S-3 (Top View) 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 AH9248 is available in TO-92S-3, SOT-23-3 and DFN-2×2-3 packages which are optimized for most applications.
