Melexis Triaxis Sin/Cos Pico-Resolver with analog output
Very fast, ASIL-capable absolute measuring sine/cosine encoder with Melexis Triaxis technology and IMC-disk (Integrated Magnetic Concentrator) based on the Hall effect for non-contact position determination of a magnet in high-speed rotary or end-of-shaft, off-axis or through-shaft applications. The IC is can be configured by I2C for various magnet arrangements such as X/Y, X/Z or Z/Y. A diametral magnet is required for control.
Features
- Sin/Cos configurable for the axes X/Y, X/Z or Z/Y
- Ratiometric Sin/Cos analog output with adjustable Voq
- Operating voltage 3.3V or 5V
- Magnetic temperature compensation selectable for NdFeB, SmCo or Ferrite
- Programmable sensitivity range 10...70mT or 40...160mT
- 1µs sampling rate per axis
- 2µs output refresh rate
- Angular speed up to 50'000 RPM
- ASIL B according to ISO 26262 SEooC (Safety Element out of Context)
- Temperature range -40...+160°C
- Package DFN-6 (6 pin; 2 x 2.5 x 1 mm)
