Integrated AMR for Cylinder Position Detection


The TSHA2101 is produced with SIP (System in Package) technology, which builds AMR sensor & ASIC in one IC. It supports both 2-wire & 3-wire applications for cylinder position detection.

The TSHA2101 is an AMR (Anisotropic Magneto Resistance) based magnetic sensor, when combined with a magnet, it becomes a non-contact switch with low power consumption, high sensitivity and high reliability device. A horizontal magnetic field parallel to the electrode of the package can be detected by an arbitrary polarity.

TSHA2101 can be used in both pull-up load and pull-down load applications.
