Description
General part information
LF21115TMR Series
LF21115TMR is a TMR 17 gauss 200nA push pull sensor omni-polar switch. This switch is a digital omni-polar magnetic switch that integrates TMR and CMOS technology in order to provide a magnetically triggered digital switch with high sensitivity, high speed, and low power consumption. It contains a TMR magnetic sensor and CMOS signal processing circuitry within the same package, including an on-chip TMR voltage generator for precise magnetic sensing, a TMR voltage amplifier and comparator plus a Schmitt trigger to provide switching hysteresis for noise rejection, CMOS push-pull output and X axis sensing direction. Typical applications are proximity detection, utility meters including gas and water meters, speed sensing, battery powered applications, rotary sensing.
