The MagnetoResistive (MR) sensor with integrated amplifier is designed for angular control applications and BrushLess DC (BLDC) motors with even-numbered pole pairs. It consists of two microchips within one package, an angle sensor and an amplifier Integrated Circuit (IC). The circuit delivers cosine and sine output signals related to the angle of a rotating magnetic field. The output voltage range is ratiometric related to the supply voltage. The Temperature Coefficient (TC) of the sensor amplitude can be compensated. A ratiometric output voltage linear to the temperature is delivered. A Power-down mode is implemented.

Applications
The KMZ60 angle sensor is dedicated for rotor position detection for BLDC motors.
Beyond that the KMZ60 is applicable for Electronic Power Steering (EPS) applications, steering angle measurement, window wiper position detection and general contactless angular measurement (e.g. throttle valves or actuators). The KMZ60 is fully automotive qualified as well as applicable for industrial and consumer applications.
Typical applications:
BLDC motor (e.g. EPS)
Window wiper position detection
Steering angle measurement
General contactless angular measurement (e.g. throttle valves or actuators)
