AH9247-W-7

AH9247 HIGH SENSITIVITY MICROPOWER OMNIPOLAR HALL-EFFECT SWITCH Description Pin Assignments NEW PRODUCT The AH9247 is a high sensitivity Hall-effect switch with internal pull-up resistor on the output, designed for battery-operation, handheld equipments. (Front View) 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 TO92S (TYPE B) 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 (B RP), the output will be turned off. (Top View) VCC 1 2 The AH9247 is available in TO92S (TYPE B), SC59 and DFN-2X2-3 packages which are optimized for most applications.
