Title:
MAGNETIC SENSOR INTEGRATED CIRCUIT, MOTOR ASSEMBLY AND APPLICATION DEVICE
Document Type and Number:
Japanese Patent JP2017216676
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an improved magnetic sensor integrated circuit, motor assembly and application device.SOLUTION: The magnetic sensor integrated circuit includes a magnetic field detection circuit. The magnetic field detection circuit includes a magnetic sensing element configured to sense an external magnetic field and output an electrical detection signal, a signal processing unit configured to perform amplification and interference rejection on the electrical detection signal to generate an analog signal, and a comparator configured to compare the analog electrical signal with a reference voltage, and output a magnet detection signal corresponding to the external magnetic field. The reference voltage is generated based on an input common-mode voltage of the magnetic field detection circuit.SELECTED DRAWING: Figure 1
