Description
The iC-TW39 is a very compact TMR-based system-on-chip solution
for 360-degree absolute angle sensing in the end-of-shaft position.
The sensor tracks the magnetic field direction in the X-Y chip plane,
with relaxed tolerances for IC placement and operating distance
to the diametrical magnet. Utilizing a high-resolution interpolator
with digital filtering and automatic error correction, the chip ensures
minimal angular error, excellent position jitter even at low speeds,
and unmatched position noise at standstill.
The fast data processing refreshes the absolute angle position every
20ns for immediate output via BiSS or SSI. In addition, incremental
ABZ signals are available with resolutions of 1 to 65,536 cycles per
revolution, or alternatively, UVW commutation signals for 1 to 32
pole-pair motors. The iC-TW39 can be configured using the bidirectional BiSS interface or SPI. Extensive status and signal quality
monitoring capabilities allow detection and notification of poor
operating conditions, as well as drive monitoring for predictive
maintenance.
