Source: Allegro MicroSystemsAllegro MicroSystems, a provider of power and sensing solutions for motion control and energy efficient systems, has unveiled ease-of-use enhancements to its high current fully integrated ACS772/3 current sensor CB package family.
These automotive grade high voltage isolation current sensors already provide economical and precise solutions for both AC and DC current sensing up to 400A. Building on that leadership and deep customer-understanding, Allegro’s new surface-mount lead form option for the CB package is the answer to many customer challenges by providing a flexible solution for space constrained applications.
The ACS772/3 family of current sensor ICs has an enhanced feature set that helps engineers simplify their bill of materials and improve efficiency in the toughest of applications:
- Small form footprint over competing solutions
- Very fast 2.5uS response time that enables overcurrent fault detection - ideal for safety-critical applications
- Enhanced working isolation voltages up to 1300 V+ for basic DC voltage, and 650 V+ for reinforced isolation DC voltage - No need for opto-isolators or other costly isolation techniques.
- High accuracy of +/-2.1% over the lifetime of the IC
These features make the ACS772/3 family ideal for a range of applications from industrial robotics to electric vehicles.
