Product Brief

High Sensitivity Micropower Omnipolar Hall-Effect Switch

Description

The AH9248 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 (B

), the output will be

turned on; if it is less than releasing point (B

the output will be turned off.

The AH9248 is available in TO-92S-3, SOT-23-3

and DFN-2×2-3 packages which are optimized for

most applications.
