Unipolar Hall Effect Switch ICs CYD9639

The CYD9639 is a highly sensitive unipolar Hall Effect switch IC. The built-in dynamic offset cancellation and temperature compensation of the pre-amplifier stage achieve 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 a single chip. 

Applications

  •  Automotive brake pedal position detection
  •  Proximity detection
  •  Speed measurement
  •  Weak magnetic field applications
  •  Solid-state switches etc.

Features

  • 3.8V to 24V operation voltage
  • High accuracy unipolar switch
  • Built-in dynamic offset cancellation
  • Open-drain output
  • A low thermal drift of magnetic sensing
