Typical Applications

Packaging

  • Magnetic sensor IC with integrated rare-earth pellet
  • Two-wire current mode PWM (pulse-width modulation) output
  • Customer-programmable position range selection and offset, bandwidth, output clamps, and temperature compensation
  • Sensitivity temperature coeff icient and offset drift preset at Allegro
  • Temperature-stable, mechanical stress immune, and low noise device output via proprietary active stress compensation and four-phase chopper stabilization design techniques
  • Wide ambient temperature range: –40°C to 150°C
  • Operates with 3.75 to 9.5 V supply voltage
  • Differential linear signal processing
  • AEC-Q100 qualified

The integrated back-bias magnet greatly simplifies packaging for the customer, requiring only a ferrous target to detect. The ATS344 is offered in a Pb free, 100% matte-tin lead-frame plated 3-pin SP package.
