Programmable linear Hall sensor Infineon TLE4998C3C featuring EEPROM memory lock and error correction

Product Overview

The TLE4998C3C is a programmable linear Hall sensor designed for highly accurate angle and position detection, as well as current measurement applications. It features a digital SPC (Short PWM Code) signal based on the SENT protocol, offering enhanced interface capabilities. The sensor provides a 16-bit resolution, digital temperature compensation, and programmable parameters stored in EEPROM with error correction. Its integrated capacitors enhance EMC performance, making it suitable for demanding automotive environments.

Product Attributes

  • Brand: Infineon Technologies
  • Package: PG-SSO-3-92
  • Certifications: SAE J2716 (for SENT protocol basis)
