Littelfuse LF21115TMR LF21115TMR Tunnelling Magneto Resistance Switch 1.8-5.5 V Supply SOT-23 -40°C to 125°C New
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.
- Tunnelling Magnetoresistance (TMR) technology, ultra low power consumption at 200nA
- X axis sensing direction, high frequency up to 50Hz
- Operation with north or south pole
- Low switching points for high sensitivity, wider airgap capability
- Excellent thermal stability, high tolerance to external magnetic field interference
- Operates with smaller magnets for cost reduction
- Operating supply voltage range from 1.8 to 5.5V (at TA = +25°C, Vcc = 3.0V)
- Supply current is 200nA typical (at TA = +25°C, Vcc = 3.0V, output open)
