General DescriptionTMR1102 is an omnipolar magnetic switch integrated the tunnel magnetoresistance (TMR) magnetic sensor and CMOS circuitry, which is able to detect the change of magnetic field and output high and low voltage signals for high accuracy position detection.

Unlike Hall/AMR sensors, TMR sensors with extremely high resistance values allows TMR1102 to achieve the supply current as low as 1.5 μA while operating in the full-time power supply mode, and maintaining the response frequency of the magnetic signal is 1 kHz. Therefore, TMR1102 can provide true continuous detection of magnetic field signals, avoiding sampling errors from the traditional time-sharing power supply mode.

Features and Benefits:(1Tunneling magnetoresistance (TMR) technology;2Low power consumption: supply current 1.5 μA;3High frequency response: typ. 1 kHz;4Omnipolar operation;5Wide range supply voltages: 1.8 V to 5.5 V;6CMOS push-pull output;7High sensitivity;8Excellent temperature stability;9High tolerance to external magnetic field interference;10RoHS & REACH compliant.

Applications:(1Utility meters: water, gas, and heat meters;2Proximity switches;3Speed sensing;4Linear and rotation position sensing;5Wake-up switch.
