Allegro Redefines Sensing with Launch of New Current Sensor ICs in Compact Packages

Allegro MicroSystems announced the launch of two new current sensor ICs - the ACS37030MY and the ACS37220MZ. Leveraging Allegro’s cutting-edge sensing technology, these ICs provide low internal conductor resistance, high operating bandwidth and reliable performance across a wide range of automotive, industrial and consumer applications.

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 to the existing 16-pin packages on the market. The new innovative designs also incorporate lower resistance, which helps to reduce power dissipation.

The ACS37030MY is a fully integrated current sensor IC with industry’s fastest response time 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 innovative 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.

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