Linear and Angular Position

Linear and Angular Position Sensing

System designers value our contactless, absolute position sensor ICs. Our robust EEPROM programmable ICs meet the accuracy requirements of stroke and rotary position sensing applications — over the complete automotive voltage and temperature range.

We also understand that wiring harness costs and deep levels of system diagnostics are important for our customers. We offer a wide range of signal output protocols, including analog, PWM, 2-wire, SPI, I2C and the fastest shared SENT protocol on the market.

Our unique, dual-die ASIL-D compliant solutions are ideal for ADAS and advanced safety applications.
