High Sensitivity Ultra-Low Power Tunneling Magnetoresistance TMR Switch
Littelfuse's TMR is a magnetically-triggered digital switch with high sensitivity and ultra-low power consumption
Littelfuse's TMR switch is a digital magnetic switch that integrates tunneling magnetoresistance (TMR) and CMOS technology to provide a magnetically-triggered digital switch with high sensitivity and ultra-low power consumption. The TMR switch contains a magnetic sensor and CMOS signal processing circuitry with an on-chip TMR voltage generator for precise magnetic sensing. A TMR voltage amplifier and comparator plus a Schmitt trigger provide switching hysteresis for noise rejection and a bandgap regulator is used to provide a temperature compensated supply voltage for internal circuits.
