TLE4929C-XAF-M28 Crankshaft applications
Overview
XENSIV™ - TLE4929C-XAF-M28 freely programmable magnetic sensor with open EEPROM
The Infineon XENSIV 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, (link to)
- TLE4929C-XAF-M28 – freely programmable sensor with open EEPROM
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
