Discover the next generation of magnetic sensing
高效功率转换
精确测量整个动态范围，提供更清晰的信号。
采用宽带隙晶体管
GAN 和 SiC 等宽带隙晶体管需要高带宽的电流传感器，XtremeSense TMR 在不牺牲精度和分辨率的情况下实现了这一点。
减少能源足迹
提供所有磁传感产品类别中最低的功耗。
隧道磁阻 (TMR) 技术
XtremeSense TMR 技术的核心是一个薄膜磁阻器件，称为“磁性隧道结”(MTJ)。在最简单的形式中，MTJ 由薄但非常坚固的绝缘层两侧的两个导电磁层组成。一个磁层具有固定的磁矩方向，另一个可以自由变化以跟随局部磁场的方向。
