TDK TAD2143 high-precision TMR angle sensor with digital output
TDK announces TAD2143 high-precision TMR angle sensor with digital output
High-precision TMR angle sensor with digital output.
Features
- TMR sensor with integrated signal processor unit
- Angle error compensation: static compensation and dynamic compensation
- Various and configurable digital outputs:
- UVW (hall switch emulation with extrapolator)
- PWM
- ENC (encoder mode, ABZ)
- SPI
- Internal diagnostic capability for high diagnostic coverage
- Continuous in operation self-tests:
- Magnet loss detection
- Maximum rotation speed detection
- Over or undervoltage detection
- Internal sensor fails
- Signal processing supervision
- Register CRC
- Self-teach-in feature for angle errors
- Industrial grade only available
- Fast response, high angular accuracy, and advanced compensation algorithms suitable for fast and accurate motor control applications
- Self-teach-in feature allows compensation of system level errors
- Very stable position measurement (over temperature and lifetime) – no need for re-calibration
- UVW mode with extrapolator allows use of same setup (sensor and magnet) for different motor topologies (pole pair numbers)
Applications
- BLDC motor commutation
- Absolute angle sensor
