iC-TW39 24-Bit Magnetic On-Axis Angle Sensor

iC-Haus iC-TW39 24-Bit Magnetic On-Axis Angle Sensor is a very compact TMR-based system-on-chip solution for 360° absolute angle sensing in the end-of-shaft position. This sensor tracks the magnetic field direction only in the X-Y chip plane, with reasonable placement tolerances of the IC. The iC-TW39 sensor signal is resolved by a high-resolution interpolator, featuring resolution-enhancing digital filtering and automatic signal error correction. This sensor is configured via SPI or the bidirectional BiSS interface, which supports encoder profiles 3 and 3S by simplifying the BiSS master connection. The iC-TW39 sensor ensures minimal angular error, excellent position jitter even at low speeds, and unmatched position noise at standstill. Typical applications include high-resolution angle sensing, brushless motor commutation (2 to 64 poles), incremental or absolute rotary encoders, and servo motor control.
