1. Product profile
1.1 General description
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.
1.2 Features and benefits
 High precision sensor for magnetic angle measurement
 Single-ended cosine and sine outputs
 Ratiometric output voltages
 T_amb = 40 C to +150 C
 Temperature compensated output signal amplitude
 Temperature related ratiometric reference voltage
 Power-down mode to enable or disable the device
 Single package angle sensor with integrated instrumentation amplifier
 RoHS compliant and free of halogen and antimony (Dark Green compliant)
1.3 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)
 Automotive, industrial and consumer applications
