BCD Semiconductor Manufacturing Limited AH9247
The AH9247 is an ultra-sensitive Hall-effect switch with digital latched output, mainly designed for battery-operation, handheld equipments. This function will reduce the average operating current of the IC. The AH9247 is available in TO-92S-3, SOT-23-3 and DFN-2×2-3 packages which are optimized for most applications.| Part No. | AH9247 |

GENERAL DESCRIPTION
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. 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 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.FEATURES
