200kHz, 1.5% Max Tolerance, 100 µΩ Internal Resistance Module-alternative Current Sensor for High Current and High Voltage Applications

The ACS772 is an automotive grade, 200 KHz Bandwidth Current Sensor IC in Allegro’s proprietary CB package. It offers a wide current sensing range (50 A to 400 A) and very low power loss achieved by the 100 μΩ internal resistance of its conductive path. The ACS772 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) or 3.3 V (ACS773).

The ACS772 is ideal for automotive applications 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.

This sensor is provided in an Allegro custom CB package offering a very small form footprint, lower ICC and higher accuracy over current sensor modules offered by competing solutions. The ACS772 has a 2.5μs response time, which is the fastest response time IC ever offered in the custom Allegro CB package.
