TMR Switches

Littelfuse TMR Switches are digital magnetic switches that integrate tunneling magnetoresistance (TMR) and CMOS technology. This technology provides a magnetically triggered digital switch with high sensitivity, and ultralow power consumption. This Littelfuse series contains a TMR magnetic sensor and CMOS signal processing circuitry within the same package. An on-chip TMR voltage generator is also included for precise magnetic sensing. A TMR voltage amplifier and comparator plus a Schmitt trigger provide switching hysteresis for noise rejection.
