The current sensor families are innovative, monolithic, isolated Hall-effect based devices that provide a fully-integrated solution in industry-leading small-sized packages.
Key features:
- Low insertion loss; power dissipation much less than shunt solution
- Able to monitor both AC and DC currents
- Smaller form factor than shunt and current transformer solutions
- 5 V, single supply operation
- Voltage isolation rating certified by TUV America
- RoHS compliant
If you need to measure more than 200 A, please see the application note, Using Allegro Current Sensors in Current Divider Configurations for Extended Measurement Range.
