TLE4997E2
Description:
The linear Hall IC TLE4997has been designed specifically to meet the demands of highly accurate rotation and position detection, as well as for current measurement applications. The sensor provides a ratiometric analog output voltage, which is ideally suited to Analog-to-Digital (A/D) conversion with the supply voltage as a reference. The IC is produced in BiCMOS technology with high voltage capability and also provides reverse polarity protection. Digital signal processing using a 16-bit DSP architecture and digital temperature compensation guarantees excellent stability over a long period of time. The minimum overall resolution is 12 bits. Nevertheless, some internal stages work with resolutions up to 20 bits.
Summary of Features:
Target Applications:
- Robust replacement of potentiometers ,no mechanical abrasion,resistant to humidity, temperature, pollution and vibration
- Linear and angular position sensing in automotive applications like pedal position, suspension control, valve or throttle position, headlight levelling and steering angle
- High current sensing for battery management, motor control, and electronic fuse
