NXP Semiconductors has announced the KMZ60, a magnetoresistive angle sensor with integrated amplifier IC. The NXP sensor uses AMR technology (AMR: anisotropic magnetoresistive) and is designed as a low cost, high-performance control device for brushless DC motor commutation.
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 in relation 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.
- High precision sensor for magnetic angle measurement
