New evaluation board from iC-Haus
The new TW39_3M evaluation board from iC-Haus combines the TMR-based iC-TW39 angle sensor with the battery-buffered Hall sensor iC-PVL to form a compact, end-of-shaft encoder solution for absolute angle measurement with additional revolution counting.
Developers can now build this high-resolution magnetic multiturn encoder solution from iC-Haus in the laboratory and put the chip duo into operation.
The kit includes the appropriate number of magnets and connection cables, so that a working encoder system is ready for testing.
The angle is resolved with up to 24 bits and supplemented by a 24-bit revolution counter. An externally applied backup voltage source ensures that iC-PVL continues to detect full revolutions without interruption after the main power supply is switched off. The low-power sensor has a current consumption of approximately 3...10 μA, thus ensuring a particularly long battery life.
The data processing of the entire encoder system is handled by the iC-TW39 singleturn device. Advanced features such as one-button on-chip calibration and automatic tracking of the optimum operating point make commissioning particularly easy and ensure optimum angular accuracy.
Communication with the encoder is via a high-performance BiSS interface. The microcontroller integrated on the TW39_3M evaluation board allows, for instance, individual adaptation of the BiSS register mapping and the integration of additional OEM data memory.
Owing to this flexibility, customer-specific additional data can be integrated into the encoder system or even complete retrofit projects can be realised.
A live demonstration of this solution will be provided at embedded world 2025.
