Allegro Introduces Surface Mount Fully Integrated Current Sensors, Easier Design Layout for High Current Density Applications

Manchester, NH, USA – Allegro MicroSystems (Allegro), a global leader in motion control and energy efficient system power and sensing solutions, announces the release of its popular high current, fully integrated ACS772/3 current sensor CB package family. Major usability improvements.

These industry-leading automotive-grade high-isolation voltage and current sensors already provide economical and accurate solutions for AC and DC current sensing up to 400A. Based on this market leadership and deep understanding of customers, Allegro offers new products for the CB package family. Surface mount leadform options provide a more flexible solution for space-constrained applications, addressing many customer challenges.

More flexible, easier and more efficient

Shaun Milano, Director of the Current Sensors Business Unit at Allegro, explained: “This is a classic ‘customer asks, we act’ with a very clearly targeted innovation model. Customers demand greater design flexibility, and we are delighted to have this These technologically innovative, powerful solutions are available in a new surface mount option to complement our popular through-hole family of products. High current PCB designs enable increased power density and efficiency, this surface mount option allows customers to These advantages are achieved through simpler manufacturing processes.”

The ACS772/3 family of current sensors provides enhanced functionality to help engineers simplify bill of materials and increase efficiency in the most demanding applications, including:

Smaller form factor than competing solutions

Very fast 2.5s response time for overcurrent fault detection, ideal for safety-critical applications

·Higher working isolation voltage up to 1300V+ for basic DC voltage.For reinforced DC voltage isolation, operating isolation voltages can be as high as 650V+, eliminating the need for opto-isolators or other expensive isolation techniques

High accuracy of ±2.1% over life cycle

These features make the ACS772/3 series ideal for a range of applications such as industrial robotics and electric vehicles.

Shaun Milano said: “Many of our customers, especially those in the green energy application industry, are striving to adopt higher operating voltages, thereby increasing the efficiency of the system and reducing costs. In solar applications, for example, increasing the system voltage can increase the The string length of battery packs, thereby reducing significant wiring and connector combinators, allows for longer panel stringing and the use of inverters with higher output ratings, reducing losses and increasing efficiency. These are important to our customers. It’s a win-win technology improvement.”
