Product information "Unipolar Hall Effect Switch Ics CYD9639, Power Supply: 3.8-24V, Supply Current: 50mA,Operating Temperature: -40 ~+125°C"

The CYD9639 is a high sensitive unipolar Hall Effect switch IC. The built-in dynamic offset cancellation and temperature compensation of pre-amplifier stage achieves accuracy magnetic sensing. The supply voltage range is from 3.8V to 24VDC and the maximum output current is 50mA. This Hall Effect switch IC integrates a Hall plate, pre-amplifier with dynamic offset cancellation, hysteresis comparator and protection circuit in single chip. 

Applications

  •  Automotive brake pedal position detection
