A33115: Precision TMR Angle Sensor with Integrated Diagnostics and Turns Counter

The A33115 is a 360° angle sensor ICs that provide contactless high-resolution angular position information based on magnetic sensing that combines TMR (Tunneling MagnetoResistance) and VH (Vertical Hall) technologies.

The device is a system-on-chip (SoC) architecture that includes two independent angle sensing channels, digital signal processing, and output options: SPI, PWM, motor commutation (U, V, W), and encoder outputs (A, B, I).

Also integrated into the devices are on-chip EEPROM technology, capable of supporting a high number of read/write cycles for flexible end-of-line programming of calibration parameters.
