• Green product (RoHS compliant)

Product Validation

Developed for automotive applications. Product qualification according to AEC-Q100.

Potential Applications

The TLE5309D angle sensor is designed for angular position sensing in safety critical automotive and non-

automotive applications. Its high accuracy and 360° measurement range combined with short propagation

delay makes it suitable for systems with high speeds and high accuracy demands such as brush-less DC (BLDC)

motors for actuators and electric power steering systems (EPS). At the same time its fast start-up time and low

overall power consumption enables the device to be employed for low-power turn counting. Extremely low

power consumption can be achieved with power cycling, where the advantage of fast power on time reduces

the average power consumption.
