MA600 Configurable Digital Magnetic Angle Sensor NOT RECOMMENDED FOR NEW QFN-16

MA600 Configurable Digital Magnetic Angle Sensor NOT RECOMMENDED FOR NEW QFN-16

The MA600 is a precision, high-bandwidth magnetic angle sensor that detects the absolute angular position of a permanent magnet, typically a diametrically magnetized cylinder on a rotating shaft.

Typical Application Circuit

Applications

• Robotics
• Multi-Turn Encoders
• Position Control

Design Notes

• Mechanical tolerance between the magnet and the sensing element translates directly into angle error; budget it before choosing the resolution.
• Match the output interface (SPI, ABZ, PWM or analog) to the MCU timing, including the latency the control loop can tolerate.
• Offset and sensitivity drift over temperature are systematic — a single-point calibration at room temperature will not hold over the operating range.
• Differential or digital outputs survive electrically noisy motor environments far better than single-ended analog ones.
