XtremeSense™ TMR Technology Sensors

Allegro MicroSystems XtremeSense™ TMR (Tunnel Magnetoresistance) Technology Sensors feature a range of high-bandwidth and ultra-low-noise integrated contact current sensors. XtremeSense TMR technology enables high magnetic sensitivity, extremely low power consumption, and smaller size compared to other magnetic technologies such as Hall, AMR, and GMR. Allegro MicroSystems XtremeSense TMR Technology Sensors are an ideal fit for high-growth industries such as automotive, industrial, and consumer goods that require higher accuracy, lower power consumption, and greater bandwidth.
