Infineon Applied sciences AG combines its confirmed experience in magnetic place sensors with its established linearized tunnel magnetoresistance (TMR) know-how to launch the XENSIV TLI5590-A6W magnetic place sensor. The sensor is available in a wafer-level package deal and is nicely suited to linear and angular incremental place detection. The system is certified for industrial and client functions in response to the JEDEC normal JESD47K and can be utilized as a substitute for optical encoders and resolvers. It’s nicely suited to positioning lenses for zoom and focus adjustment in cameras.

The TLI5590 is a low area sensor with Infineon TMR know-how which was developed for high-volume sensor programs. Consequently, the sensor provides ultra-high sensitivity, low jitter, and low energy consumption. In comparison with linear Corridor sensors, TMR sensors supply higher linearity, decrease noise, and decrease hysteresis. The excessive signal-to-noise ratio and the decrease energy allow cost-effective magnetic designs with decrease battery consumption.

Consequently, the brand new sensor permits correct detection with quickly altering instructions. The TLI5590 consists of two TMR Wheatstone bridges, the place the TMR resistance depends upon the path and energy of the exterior magnetic area. Together with a multipole magnet, every bridge gives a differential output sign, i.e., sine and cosine indicators. These may be additional processed for relative place measurement.

The sensor is housed in an excessive small 6-ball wafer stage package deal SG-WFWLB-6-3. Because of the greater integration density, the sensor dimension has been diminished, which helps miniaturization and place detection in microsystems. The TLI5590-A6W permits effective measurement with a really excessive accuracy of higher than 10 µm, which is achieved by utilizing an appropriate linear or rotary magnetic encoder. With an prolonged working temperature vary of as much as +125°C, the sensor can be utilized flexibly in varied industrial and client functions. As well as, its excessive temperature stability makes it the proper selection to be used in harsh environments.
