These ICs have been designed to 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 provide 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 many of the existing 16-pin packages on the market. The 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 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.
