Magnetic current sensors are replacing sense resistors and current transformers

Modern cars have become increasingly power hungry. Even the "least electrified" vehicles include advanced electronics for infotainment, safety, and engine control. Fully electric vehicles further add high-voltage power domains to charge and drive. Each of these systems shares the need for power monitor... Read more...

Allegro’s XtremeSense™ TMR technology (Tunnel Magnetoresistance) provides the highest magnetic sensitivity, the lowest power consumption, and the smallest size by comparison to other magnetic technologies such as Hall, AMR, and GMR. Accelerating various applications from renewable energy systems, xEV, and connected consumer devices, Allegro’s XtremeSense TMR technology... Read more...

Due to degradation and aging effects, devices no longer run at their optimal performance. Once detected, maintenance can be triggered thanks to continuous "condition monitoring" based on various sensor types. Read more...
