3kV_RMS Isolated Hall-Effect Current Sensor with 580V_RMS Working Voltage and Over-Current Detection, AEC-Q100 Qualified

Datasheet

Description

The MCQ1805 is an automotive-grade, linear Hall-effect current sensor for AC or DC current sensing. The Hall array is differential, which cancels out any stray magnetic field.

A primary conductor with a low resistance allows the current to flow close to the IC, which contains high-accuracy Hall-effect sensors. This current generates a magnetic field that is sensed at two different points by the integrated Hall-effect transducers. The magnetic field difference between these two points is then converted into a voltage that is proportional to the applied current. A spinning current technique is used for a low, stable offset.

The galvanic isolation between the pins of the primary conductive path and the sensor leads allows the MCQ1805 to replace optoisolators and other isolation devices.

The MCQ1805 provides fast over-current detection (OCD) to monitor the system for over-current (OC) faults.

The MCQ1805 requires a minimal number of readily available, standard external components. The device’s small SOIC-8 footprint saves board area and makes it well-suited for space-constrained applications.

The EVCS1805-S-00A is an evaluation board designed to demonstrate the capabilities of the MCS1805 series, which are linear Hall-effect current sensors for AC or DC current sensing with integrated over-current detection (OCD). The differential Hall array cancels out stray magnetic field. The MCS1805 series provides two power supply options (3.3V or 5V) and current ranges of 5A to 50A to optimize accuracy in different applications.

The output voltage (V_OUT) is proportional to the applied current flowing through the primary conductor. The galvanic isolation between the primary conductive path pins and the sensor leads allow the MCS1805 to replace optoisolators or other expensive isolation devices.

The MCS1805 is available in an SOIC-8 package.
