ACS773.: 200kHz, 1.5% Max Tolerance, 100 µΩ Internal Resistance module-alternative current sensor for high current and high voltage applications

The ACS773 is an automotive grade, 200KHz Bandwidth Current Sensor IC in Allegro’s proprietary CB package. It offers a wide current sensing range (50A to 400A) and very low power loss achieved by the 100 μΩ internal resistance of its conductive path. The ACS773 achieve the highest performance in the CB package family with an accuracy of +/-2.1% over the lifetime of the IC from room to hot temperature. The 2.5 μs response time enables overcurrent fault detection in safety-critical applications while the Reinforced Galvanic Isolation reduces the bill of materials. It works off of a single 5 V supply (ACS772.）或3.3V（ACS773）。

The ACS773 is ideal for Automotive application such as OBC, DC/DC converters and Inverter control as well as for industrial applications such as motor control, load detection and management and power supplies.

该传感器设置在Allegro定制CB封装中，提供非常小的表单足迹，较低的ICC和通过竞争解决方案提供的电流传感器模块的更高精度。ACS773具有2.5μs响应时间，这是在定制孔和定制 - 表面贴装Allegro CB包中提供的最快响应时间IC。
