The ACS710 consists of a precision linear Hall sensor integrated circuit with a copper conduction path located near the surface of the silicon die. Applied current flows through the copper conduction path, and the analog output voltage from the Hall sensor linearly tracks the magnetic field generated by the applied current. The accuracy of the ACS710 is maximized with this patented packaging configuration because the Hall element is situated in extremely close proximity to the current to be measured.

Allegro专有集成屏蔽技术提供了对电流导体dV/dt和杂散电场的高水平抗扰度，确保在高压侧应用中输出低纹波和低偏移漂移。亚博尊贵会员

The voltage on the Overcurrent Input (VOC pin) allows customers to define an overcurrent fault threshold for the device. When the current flowing through the copper conduction path (between the IP+ and IP– pins) exceeds this threshold, the open drain Overcurrent Fault pin will transition to a logic low state. Factory programming of the linear Hall sensor inside of the ACS710 results in exceptional accuracy in both analog and digital output signals.

用于电流传感的铜通道的内阻通常为1 mΩ，以实现低功耗。此外，电流传导路径与低电压传感器输入和输出电隔离。这使得ACS710系列传感器可用于需要电气隔离的应用中，而无需使用光隔离器或其他昂贵的隔离技术。亚博尊贵会员

ACS710采用小型表面贴装SOIC16封装。引线框架镀有100%亚光锡，与标准无铅印刷电路板组装工艺兼容。在内部，该设备是无铅的，除了倒装芯片高温铅基焊料球，目前免除RoHS。设备在出厂前已完全校准。
