Core Insights - Allegro MicroSystems has introduced the ACS37200, a galvanically isolated current sensor that significantly enhances efficiency and power density in high-current applications, particularly in HEV/EVs, industrial automation, AI data centers, and solar inverters [1][4] Group 1: Efficiency and Power Loss Reduction - The ACS37200 features an ultra-low conductor resistance of 50 µΩ, which reduces power loss by 90% compared to traditional 0.5mΩ shunt resistors, decreasing wasted energy from 5 watts to just 0.5 watts [2][10] - This reduction in power loss directly contributes to improved HEV/EV range and lowers operational costs for data centers [2] Group 2: Size and Power Density - The ACS37200 is nearly 70% smaller than its predecessor, the ACS772, and offers a total footprint that is 20 times smaller than traditional shunt solutions, achieving a 95% reduction in board space [3][10] - The minimal heat generation allows for the elimination of bulky heatsinks, further enhancing compactness and power density [3] Group 3: Design Simplification and Safety - The fully integrated design of the ACS37200 simplifies the design process by replacing multiple discrete components with a single factory-calibrated IC, which reduces the bill of materials and supply chain complexity [5][10] - The sensor is certified to UL 62368-1, enhancing system safety and reliability by removing the need for complex high-voltage isolation designs [5][10]
