High Accuracy Current Sensor with 400Khz Bandwidth using ACS37002
This is a high accuracy current sensor project build using ACS37002 IC from Allegro, which is a fully integrated Hall-effect current sensor with 0.85mOhms integrated conductor. A fast overcurrent alert output, programmable gain settings and analog linear voltage outputs are key features of this project.
Features
- Operating Supply 5V DC
- Output-VO 40mV/A, 50mV/A, 60mV/A, 30mV/A (50A,40A,33.3A,66.7A)
- Four Configurable Gain Settings Using Jumper J1, J2
- Adjustable Fast Over Current Fault 1us Response Time
- Over Current Output Normally High Goes Low @ Fault Condition (OCF)
- High Operating Bandwidth for Fast Control Loops
- 400Kz Frequency Bandwidth, 2us Response Time
- Very Low Sensitivity Error 1%
- 6mV Maximum Offset Voltage Over Temperature
- PCB DIMENSIONS 42.55 X 41.59 mm
