Allegro MicroSystems ACS37035 AEC-Q100 1MHz Hall-Effect Current Sensor
Allegro MicroSystems ACS37035 AEC-Q100 1MHz Hall-Effect Current Sensor is ideal for high-frequency switching applications, serving as a superior alternative to bulky and less efficient current transformers. This sensor integrates a sensing element and signal processing into a small SOIC-16 wide-body package, reducing both bill-of-materials and PCB space and improving the overall design quality and efficiency. Two Hall plates are utilized for differential sensing, effectively subtracting interfering common-mode magnetic fields for robust performance in loud environments. Additionally, the low internal resistance of typically <1mΩ on the conductive path contributes to minimal power loss and increased efficiency in applications. Allegro MicroSystems ACS37035 Sensor is suitable for xEV onboard chargers, xEV DC-DC, and server power supplies.Features
