Low-Cost Hall-Effect Sensor Family

The HAL 2xy Hall switch family is produced in CMOS technology. The sensors include a temperature-compensated Hall plate with active offset compensation, a comparator, and an open-drain output transistor.

FEATUREs
✦ Operates from 3.8 V to 24 V supply voltage
✦ Operates with static magnetic fields and
   dynamic magnetic fields up to 10 kHz
✦ Overvoltage protection at all pins
✦ Reverse-voltage protection at VDD pin
✦ Magnetic characteristics are robust
   against mechanical stress effects
✦ Short-circuit protected open-drain 
   output by thermal shut down
✦ Constant switching points over a wide
   supply voltage and temperature range
✦ The decrease of magnetic flux density
   caused by rising temperature in the 
   sensor system is compensated by a built-in
   negative temperature coefficient of the
   magnetic characteristics
✦ High temperature stability for automotive
   or industrial applications
✦ High ESD rating

Major Applications
The HAL 2xy is the optimal system solution
for applications, such as:
✦ Endposition detection
✦ RPM measurement of motors in various
   applications, such as power window
✦ Brushless DC motors
✦ RPM measurements in flow meters
✦ Replacement of micro switches
