Current Transducers

Current transducers are electrical and electronic devices used to measure and detect current in electrical circuits. The ACS754SCB-200-PFF is a high-accuracy, low-power current transducer that enables precise and accurate measurements of AC and DC currents up to 200 Amps.

Application Field

The main application field of the ACS754SCB-200-PFF is measuring the absolute value of average current of a DC or AC waveform, usually for Motor Control or Automation applications. It is used for measuring an input current in automotive applications such as powertrain, engine control, and chassis systems. It is also widely used in medical device equipment where critical current measurements are needed.

Working Principle

The ACS754SCB-200-PFF uses the magnetic field based Hall effect principle. It detects current by sensing the magnetic field which is created when current passes though the device. The magnetic field will make the Hall sensor inside the device to generate an analog voltage output, which is proportional to the applied current.The output voltage of the ACS754SCB-200-PFF has a linear correlation with the sensed current, and can be converted to an analog signal or a digital (I2C or SPI) signal for further data analysis. The output voltage range is from -5V to +5V, and it is reverse-polarity protected. The power consumption is very low, about 20mW, making the device suitable for low-power applications.The output of the ACS754SCB-200-PFF is highly accurate, with a typical accuracy over temperature of ±3.0% and common mode rejection (CMR) of 400V. The typical thermal offset is 0.02% of full-scale. It has a Minimum Zero Current Detectability of 400nA (typical) and Zero Current Drift of 0.5µV/°C (typical).The ACS754SCB-200-PFF is protected against low current-sensing miswiring and overcurrent situations with its open-wire and overload detection functions. The device also has built-in burn-in tests and a diagnostic feature that helps the user to detect any type of fault.The package of the ACS754SCB-200-PFF is a compact surface-mount device (SMD) in a small SOT-23-3 package, making it easy to use and very suitable for applications with space constraints.In summary, the ACS754SCB-200-PFF is a high-accuracy, low-power current transducer suitable for automotive, medical device, and industrial applications, due to its highly accurate and reliable sensing solutions.
