Top Features

Packaging

  • Contactless 0° to 360° angle sensor IC, for angular position, rotational speed, and direction measurement
    • Capable of sensing magnet rotational speeds targeting 12.5-bit effective resolution with 300 G field; higher effective resolution possible at higher field strengths
    • Circular Vertical Hall (CVH) technology provides a single channel sensor system, with air gap independence
  • On-chip 32 segment linearization to improve angle accuracy
    • Reduces impact of magnet to sensor misalignment
    • Reduces impact of imperfect magnetization of target magnet
  • Developed as a Safety Element out of Context (SEooC) in accordance with ISO 26262:2011 requirements for hardware product development for use in safety-critical applications.
  • High diagnostic coverage
    • On-chip diagnostics include logic built-in self-test (LBIST), signal path diagnostics, and watchdogs to support safety critical applications
    • 4-bit CRC on SPI
  • On-chip EEPROM for storing factory and customer calibration parameters
    • Single-bit error correction; dual-bit error detection, error correction control (ECC)
  • Supports operating in harsh conditions required for automotive and industrial applications, including direct connection to 12 V battery
    • Operating temperature range from –40°C to 150°C
    • Operating supply voltage range from 3.7 to 18 V, absolute maximum of 28 V continuous
      ♦Can support ISO 7637-2 Pulse 5b up to 39 V
