Redefining sensing with new current sensor ICs in compact packages

Allegro MicroSystems, Inc. has launched two new current sensor ICs – the ACS37030MY and the ACS37220MZ. Using its cutting-edge sensing technology, these ICs deliver low internal conductor resistance, high operating bandwidth and reliable performance across various automotive, industrial and consumer applications.

“We’re excited to introduce our latest current sensor ICs as Allegro continues to push the boundaries of sensor IC technology,” said 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.”

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

The ACS37030MY is a fully integrated current sensor IC with the industry’s fastest response time to protect wide bandgap GaN devices. It combines Hall-effect and inductive coil signal paths to sense current over a wide frequency range. This innovative package offering allows a product that is 5x faster than existing solutions and 40% smaller. ACS37030 is also available in a narrow-body package for lower isolation needs.

The ACS37220MZ is 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 device package offers a 40% smaller solution size and lower resistance for lower power dissipation.
