TLE4929C-XAN-M28 pre-programmed

Overview

XENSIV(TM) - TLE4929C-XAN-M28 pre-programmed Hall-based crankshaft sensor

The Infineon TLE4929 is an active Hall sensor ideally suited for crankshaft applications and similar industrial applications, such as speedometer or any speed-sensor with high accuracy and low jitter capabilities.

We offer two versions of TLE4929 crankshaft sensors:

  • TLE4929C-XAN-M28 – pre-programmed sensor
  • TLE4929C-XAF-M28 – freely programmable sensor with open EEPROM (link to)

The sensor comes in a RoHs compliant three-pin package, qualified for automotive usage. It has two integrated capacitors on the lead frame. These capacitors increase the EMC resistivity of the device. A pull-up resistor RLoad is mandatory on the output pin and determines the maximum current flowing through the output transistor.

 

Summary of Features

  • Differential Hall speed sensor to measure speed and position of tooth/pole wheels
  • Switching point in middle of the tooth enables backward compatibility
  • Robustness over magnetic stray-field due to differential sensing principle
  • Digital output signal with programmable output-protocol including  diagnosis interface
  • Direction detection and Stop-Start-Algorithm
  • High accuracy and low jitter
  • High sensitivity enable large air-gap
  • End-of-line programmable to adapt engine parameters
  • Can be used as a differential Camshaft sensor
  • Automotive operating temperature range
