Description

Top Features

Packaging

The ATS344 device is a high precision, back-biased programmable Hall effect linear sensor integrated circuits (IC) with a configurable current mode pulse width modulated output, for both automotive and non-automotive applications. The signal path of the ATS344 provides flexibility through external programming that allows the generation of an accurate, and customized output response from a ferro-magnetic target perturbation.

The ATS344 incorporates a 2-wire current mode PWM output in order to help minimize pin count for remote sensors. It also includes on-chip EEPROM technology, capable of supporting up to 100 read/write cycles, for flexible end-of-line programming of calibration parameters. The ATS344 is ideal for automotive applications requiring high resolution detection of long stroke (>5mm) linear motion.

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.

  • 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
