Overview
Data Sheet High Sensitivity Micropower Omnipolar Hall-Effect Switch AH9249 General Description 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 re...
