ACS37002：400 kHz，高精度电流传感器，具有引脚可选的收益

The ACS37002 is a 400kHz fully integrated Hall-Effect current sensor with very high accuracy, making it ideal for use in control loops of the most demanding power conversion applications. Current flows through the internal conductor coupling the magnetic field generated to the Hall sensor IC. As a result of no physical connection between the current and the IC, high voltage isolation is achieved. The current is sensed differentially by two Hall plates that subtract out interfering external common-mode magnetic fields. The sensor is factory-trimmed to provide high accuracy over the entire operating range without the need for customer programming.

传感器具有模拟输出和用于噪声环境中的信号完整性的参考输出。包括快速过电流故障输出，具有通过模拟输入引脚具有用户可配置的阈值，提供短路检测和增强的系统保护。该传感器还在同一设备中具有四个用户可选的增益选项，其具有两个逻辑输入，而无需额外的组件。这为设计人员提供了灵活性，并最大限度地减少了需要不同电流传感范围的系统的整体材料清单。
