Allegro MicroSystems ACS37100 10MHz TMR Current Sensor Now at Mouser Electronics

December 17, 2025 - Mouser Electronics, Inc., the industry's leading New Product Introduction (NPI) distributor with the widest selection of semiconductors and electronic components, is now stocking the ACS37100 10MHz TMR current sensor from Allegro MicroSystems.

Allegro Microsystems ACS37100 current sensor is factory-trimmed to provide high accuracy over the entire operating range. This feature eliminates the need for customer programming. The current is sensed differentially by two tunneling magnetoresistance (TMR) elements that subtract out interfering external common-mode magnetic fields. 

The ACS37100 current sensor is designed to enable system designers to unlock the full potential of fast-switching GaN and SiC FETs. Tailored to the needs of electric vehicles (xEVs), clean energy power conversion systems, and AI data center power supplies, the ACS37100 achieves an industry-leading 50 ns response time, providing the high-fidelity data needed for optimal efficiency and protection in demanding high-frequency applications.
