Diodes Incorporated AH9247
The AH9247 is a high sensitivity Hall-effect switch with internal pullup resistor on the output, designed for battery-operation, handheld equipments. This function will reduce the average operating current of the IC. The AH9247 is available in TO92S (TYPE B), SC59 and DFN-2X2-3 packages which are optimized for most applications.| Part No. | AH9247 |

DESCRIPTION
A chopper stabilized amplifier improves stability of magnetic switch points. A sleep-awake logic controls the IC in sleep time or awake time. 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. 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.
