ACS37612：独立无芯差动电流传感器IC

The ACS37612 is a standalone coreless current sensor IC that provides an economical and precise solution for AC and DC current sensing without requiring a magnetic concentrator core or a shield. The ACS37612 measures currents from 200A to >1000A flowing through a PCB or a busbar with a typical accuracy of 1%.

用于测量磁场的基于差分霍尔的传感拓扑几乎消除了共模杂散磁场的错误，而不需要竞争解决方案所需的层压屏蔽，这减少了设计尺寸和材料清单（BOM）。通过这种简单组件的无关性质实现高隔离性。240kHz带宽使其成为逆变器相电流检测，负载检测和管理，电源和DC / DC转换器，其中需要快速切换。高响应时间使安全关键应用中的过电流故障检测能够。雷竞技最新网址A40°C至150°C环境工作温度和恒星ESD评级使其为苛刻的汽车环境做好准备。

The ACS37612 is offered in a low-profile 8-pin surface mount TSSOP package (thin-shrink small outline package, suffix LU) that is ideal for space-constrained applications, while allowing simple surface mount assembly.
