Additional Details

The TLE4966-3K typically operates with a supply voltage range of 3.0 V to 32 V. The output switches low when the magnetic field strength exceeds the operate point (BOP) and switches high when the field strength falls below the release point (BRP). The integrated hysteresis ensures stable switching behavior. The sensor is available in a small PG-SSO-3-2 package, making it suitable for compact designs. It is designed to meet stringent automotive quality standards and is AEC-Q100 qualified. It is resistant to mechanical stress and electromagnetic interference (EMI). The integrated protection features such as reverse voltage and short-circuit protection, contribute to the overall robustness and reliability of the sensor in challenging operating conditions. The precise and stable operation makes the TLE4966-3K an ideal choice for critical position sensing applications in automotive and industrial sectors.
