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.

KMZ60 NXP Semiconductors Angle sensor with integrated amplifier connected to ground. Pin VTEMP delivers a temperature dependent output voltage VO(TEMP) in both cases, which is tracking ratiometric with the supply voltage. It uses the internal PTAT reference and can be left open or connected to ground or preferably to VCC if not used. The pin POWERDOWN_EN input switches the device into Power-down mode and sets the pin VOUT1 and pin VOUT2 output to high impedance and disables pin VTEMP.
