General Description:The OH9248 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 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
