KMZ60 Angle sensor with integrated amplifier Rev. 2 7 February 2014 Product data sheet 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 = 40 Cto+150 C amb 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 SO8KMZ60 NXP Semiconductors Angle sensor with integrated amplifier 1.4 Quick reference data Table 1.
