Current-Sensor-ICs
High-Precision, High-Bandwidth, Programmable Core-Based Current Sensor with Fault Detection
ACS37503
The Allegro ACS37503 offers a new level of precision and flexibility for core-based current sensing designs. This fully programmable Hall-effect sensor allows engineers to fine-tune sensitivity, offset, and fault thresholds to achieve industry-leading accuracy with their chosen magnetic core. Its high-bandwidth (350 kHz) and fast response time make it an ideal solution for accurately tracking current in high-frequency automotive inverters, DC/DC converters, and other safety-critical applications.
