ACS37610: Low Noise, Standalone, Coreless Differential Current Sensor IC with Overcurrent and Overtemperature Detection

The ACS37610 provides a highly accurate method of measuring 100 A to >4000 A flowing through a busbar or a PCB without needing a concentrator core or a U-Shaped Magnetic Shield reducing system complexity, bill of material (BOM), cost, footprint, and weight. The differential measurement provides excellent immunity to stray magnetic fields without the need for a magnetic shield that often slows down the response time and adds non-linearity error.

The ACS37610 features advanced Hall elements, resulting in a 2.5× improvement in signal-to-noise ratio (SNR) and a 2× lower noise relative to the ACS37612 while achieving a typical accuracy of 1% across an extended ambient temperature range: –40°C to 150°C. The lower noise provides superior resolution required for accurate torque control, while the sensor’s 4× higher sensitivity range enables flexible busbar and PCB designs

专用过电流和过热的故障引脚，250kHz带宽和一系列内置诊断，使其成为安全关键型应用的理想选择。亚博尊贵会员用户可编程性提高了准确性，这允许设备在应用中优化并取消由于机械组装公差而取消误差。

The ACS37610 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.
