Strommesssensoren (Current Sensors) auf Hallsensor-Basis

The current sensor IC 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.
