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.

Features
  • TMR technology supports operating point thresholds from 4 Gauss to 35 Gauss
  • Ultra-low power consumption: 200 nA
  • Operation with north and south pole / X-axis or Z-axis sensing direction
  • Available in uni-polar, omni-polar, and bi-polar (latching) operating modes
  • Output type: push-pull or open-drain
Applications
  • Proximity detection
  • Utility meters including gas, water, and heat meters
  • Position and speed sensing
  • Rotary sensing
  • Motor and fan control
  • Solid-state switches
