Allegro MicroSystems launches ACS37017 current sensor

Allegro MicroSystems, Inc. (NASDAQ: ALGM) announced the release of the ACS37017, a Hall-effect current sensor designed for accuracy in power electronics applications. The Manchester, New Hampshire-based company stated the sensor achieves 0.55% typical sensitivity error over lifetime and temperature.

The ACS37017 completes what Allegro describes as a three-product lineup addressing different design priorities in power electronics. The existing ACS37100 offers 10-MHz bandwidth for speed-focused applications, while the ACS37200 features a 50 µΩ conductor for power density optimization. The new ACS37017 targets accuracy requirements.

"Our philosophy is simple: we want to give engineers the right tool for the job," said Matt Hein, Business Line Director of Current Sensors at Allegro MicroSystems. "We don't force a compromise."

The sensor incorporates what Allegro calls a proprietary compensation architecture intended to maintain measurement precision as temperatures change or components age. The device integrates a voltage reference that the company states eliminates the need for external precision voltage reference components.

Key specifications include reinforced isolation for high-voltage systems and a surface-mount leaded package design. The sensor is positioned for use in applications including AI data centers, electrified vehicles, and clean energy systems.

Engineering samples and preliminary datasheets for the ACS37017 are available through the company's website. Allegro MicroSystems develops power and sensing solutions for automotive, clean energy, and industrial automation markets.

The information is based on a company press release statement.
