Allegro MicroSystems 0A to 400A Integrated Current Sensor ICs
Allegro MicroSystems 0A to 400A Current Sensor ICs with Integrated Conductor are fully integrated solutions that provide high accuracy and reliability. The 0A to 400A Integrated Current Sensor ICs are automotive-grade devices that can take the heat and deliver highly accurate open-loop current sensing in the harshest applications environments. The 100µΩ CB package with high isolation is designed for sensing up to 400A.
The Allegro MicroSystems 0A to 400A Integrated Current Sensor ICs feature products that include the ACS72981 high-precision linear hall-effect-based current sensor IC with a 200μΩ current conductor, the ACS772 200kHz, 1.5% max tolerance, 100µΩ internal resistance module-alternative current sensor, working off of a single 5V supply, and the ACS773 200kHz, 1.5% max tolerance, 100µΩ internal resistance module-alternative current sensor, working off of a single 3.3V supply.
