Improved Surface-mount Current Sensors
Improved Surface-mount Current Sensors

The high current fully integrated ACS772/3 current sensor “CB” package family from Allegro MicroSystems now benefits from new ease-of-use enhancements. These surface-mount, automotive grade high voltage isolation current sensors already provide economical and precise solutions for both AC and DC current sensing up to 400A. The surface-mount leadform option is an answer to customer challenges by providing a flexible solution for space constrained applications.


Easy handling and layout


The enhanced feature set helps engineers simplify their bill of materials and improve efficiency in tough applications. The current sensors now benefit from a small form footprint, a fast 2.5µS response time (allows overcurrent fault detection), improved working isolation voltages up to 1300kV+ for basic DC voltage, and 650V+ for reinforced isolation DC voltage. There is no need for opto-isolators or other isolation techniques. Last, they have an accuracy of +/-2.1% over the lifetime of the IC.
