Working Principle

The working principle of the MCZ33904C5EK is based on a Hall-effect current sensing technology. The device’s single-channel sensing technique utilizes a gallium arsenide (GaAs) Hall effect based semiconductor junction as the input. This junction has a negative temperature coefficient when a magnetic field is applied. When current passes through this junction, the magnetic field changes, producing a voltage proportional to the current. This voltage is then amplified, conditioned, and converted to a digital signal that is then used by a microcontroller or other processor to measure current levels.

The MCZ33904C5EK offers a precise measurement solution with a programmable gain of up to 8x. This allows for precise current measurements even in cases where small current changes can have a large impact on a system. It also offers a programmable offset feature which allows the measurement range to be adjusted without having to recalibrate the sensor. The device also comes with several safety features that help ensure accuracy and safety, such as undervoltage lockout, overvoltage indication, and thermal shutdown.
