[Micronas]

The HAL 1xy Hall switch family is designed for home appliances and industrial applications. The sensors are produced in CMOS technology and include a temperature-compensated Hall plate with active offset compensation, a comparator, and an open-drain output transistor.

FEATUREs
◆ Temperature ranges
    – C (Commercial, TJ = 0 °C to +85 °C)
    – I (Industrial, TJ = 20 °C to +125 °C)
◆ 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 home appliances and industrial applications
◆ High ESD rating
