A1339: Precision, High Speed, Hall-Effect Angle Sensor IC with Integrated Diagnostics for Safety-Critical Applications

The A1339 is a 360° angle sensor IC that provides contactless, low latency, high-resolution angular position information based on magnetic Circular Vertical Hall (CVH) technology. It has a system-onchip (SoC) architecture that includes: a CVH front end, digital signal processing, and motor commutation (UVW) or encoder outputs (A, B, I). 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 A1339 is ideal for automotive applications requiring 0° to 360° angle measurements, such as electronic power steering (EPS), rotary PRNDLs, and throttle systems.

The A1339 supports customer integration into safety-critical applications.

The A1339 is available in a dual-die 24-pin eTSSOP and a single-die 14-pin TSSOP package. The packages are lead (Pb) free with 100% matte-tin leadframe plating.

ASIL LogoAllegro’s single and dual die A1339 devices were designed in accordance with ISO26262:2011 requirements for hardware product development for use in safety-critical applications(pending assessment). The single die version was designed to meet ASIL B requirements and the dual die was designed to meet ASIL D requirements when integrated and used in conjunction with the appropriate system level control, in the manner proscribed in the A1339 Safety Manual.

  • Contactless 0° to 360° angle sensor IC, for angular position, rotational speed, and direction measurement
    • Capable of sensing magnet rotational speeds targeting 12b effective resolution with 900 G field
    • Circular Vertical Hall (CVH) technology provides a single channel sensor system supporting operation across a wide range of air gaps
  • Developed in accordance with ISO 26262:2011 requirements for hardware product development for use in safety-critical applications (pending assessment)
    • Single die version designed to meet ASIL B requirements when integrated and used in conjunction with the appropriate system-level control, in the
      manner proscribed in the A1339 Safety Manual
    • Dual die version designed to meet ASIL D requirements when integrated and used in conjunction with the appropriate system-level control, in the manner proscribed in the A1339 Safety Manual
  • High diagnostic coverage
    • On-chip diagnostics include logic built-in self-test (LBIST), signal path diagnostics, and watchdogs to support safety-critical (ASIL) applications
    • 4-bit CRC on SPI
  • On-chip EEPROM for storing factory and customer calibration parameters
    • Single-bit error correction, dual-bit error detection through the use of error correction control (ECC)
  • Supports harsh operating 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 4.0 to 16.5 V
      • Can support ISO 7637-2 Pulse 5b up to 39 V
  • Low power mode and turns counter enable tracking of motor position even when vehicle is turned off
  • Multiple output formats supported for ease of system integration
    • ABI/UVW output provides high resolution, low latency, and PWM for initial position
    • 10 MHz SPI for low latency angle and diagnostic information; enables multiple independent ICs to be connected to the same bus
    • Output resolution on ABI and UVW are selectable
  • Multiple programming / configuration formats supported
    • The system can be completely controlled and programmed over SPI, including EEPROM writes
    • For system with limited pins available, writing and reading can be performed over VCC and PWM pins. This allows configuring the EEPROM in production line for a device with only ABI/UVW and PWM pins connected.
  • Stacked dual die construction to improve die-to-die matching for systems that require redundant sensors
  • Reduces magnet misalignment impact on die-to-die matching for a given magnet diameter, relative to “side-by-side” dual die orientation
