ACS772 200kHz Automotive Current Sensor ICs

Allegro Microsystems ACS772 200kHz Automotive Galvanically Isolated Current Sensor ICs offer a wide current sensing range (50A to 400A) and very low power loss in a proprietary CB package. The ACS772 achieves high performance with an accuracy of ±2.1% over the lifetime of the IC from room to hot temperature. The 2.5μs response time allows overcurrent fault detection in safety-critical applications while the reinforced galvanic isolation reduces the bill of materials. Furthermore, the ACS772 operates off of a single 5V supply.
