Monolithic Power Systems (MPS) MagAlpha MAQ850 8-Bit Angle Encoders
Monolithic Power Systems (MPS) MagAlpha MAQ850 8-Bit Angle Encoders are designed to replace analogic potentiometers or rotary switches. These encoders are for slow operation in Human-Machine Interfaces (HMIs) and manual controls with a rotating speed below 200rpm. The sensor detects the absolute angular position of a permanent magnet attached to a rotating shaft and outputs a Pulse-Width Modulation (PWM) waveform. These encoders feature configurable magnetic field strength thresholds, which allow for the implementation of a push or pull button function.
The MAQ850 8-Bit encoders on-chip Non-Volatile Memory (NVM) stores configurable parameters, such as the reference zero angle position and magnetic field detection threshold. These encoders are available in QFN-16 (3mm x 3mm) package and are AEC-Q100 qualified. Typical applications include rotary knob control interfaces, manual controls, encoders, automotive, and white goods.
