- Efficiency Breakthrough: Allegro's ACS37200 current sensor features an industry-leading 50 µΩ conductor resistance, reducing power loss by 90% compared to traditional 0.5 mΩ resistors, allowing a 100A design to consume only 0.5 watts, significantly enhancing efficiency for electric vehicles and data centers.
- Space Optimization: The new sensor's compact 100 mm² PSOF package is 70% smaller than the previous ACS772, resulting in a 95% reduction in footprint compared to traditional shunt solutions, enabling designers to achieve higher power density in smaller spaces and lower production costs.
- Design Simplification: The ACS37200 integrates multiple components, replacing traditional shunt resistors and isolation amplifiers, which simplifies the design process, reduces the bill of materials (BOM) costs, and enhances system safety and reliability.
- Market Demand Response: Allegro's Business Line Director Matt Hein noted that customers increasingly demand higher power density, and the launch of the ACS37200 not only meets this need but also provides greater design flexibility for future e-Mobility and clean energy systems.
