Allegro introduces new sensor ICs to market

Utilising Allegro's sensing technology, these ICs boast features such as low internal conductor resistance, high operating bandwidth and reliable performance across a range of applications including automotive, industrial and consumer.

“We’re excited to introduce our latest current sensor ICs, as Allegro continues to push the boundaries of sensor IC technology,” commented Ram Sathappan, Vice President of Global Marketing and Applications at Allegro MicroSystems. “Our newest sensors establish new standards for precision and reliability, empowering customers to overcome design and efficiency standards, while also demonstrating how our technology is driving a smarter, more efficient future.” 

Allegro’s new current sensor ICs are designed for precise current sensing in a compact and durable package. Featuring a widebody design, the ACS37030MY and ACS37220MZ deliver higher isolation in a 40% smaller footprint compared with existing 16-pin packages on the market. The new designs also incorporate lower resistance, which helps to reduce power dissipation. 

The ACS37030MY is a fully integrated current sensor IC with one of the fastest response times for protection of wide bandgap GaN devices. It uses a combination of Hall-effect and inductive coil signal paths to sense current over a wide frequency range. This package offering enables a product which is both 5x faster than existing solutions, but also 40% smaller. ACS37030 is also available in a narrow-body package for lower isolation requirements. 

Additionally, the ACS37220MZ fully-integrated, Hall-effect current sensor features a 150kHz bandwidth and fault pin. This device is designed for value-line current sensing applications as a successor to the ACS724/5 family of products. The new package of the ACS37220MZ offers a 40% smaller solution size and lower resistance for lower power dissipation.
