General Description:TMR134x is an omnipolar magnetic switch integrated the tunnel magnetoresistance (TMR) magnetic sensor and open-drain 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 TMR134x 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, TMR134x can provide true continuous detection of magnetic field signals, avoiding sampling errors from the traditional time-sharing power supply mode.

TMR134x allows a wide range of operating supply voltages from 1.8 V to 5.5 V with excellent temperature characteristics, and can meet the requirements of most applications.

TMR134x is available in two compact SOT23-3 and LGA3L (2 mm × 1.5 mm × 0.63 mm) packages.


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


Applications:(1)Utility meters: water, gas, and heat meters;(2)Proximity switches;(3)Speed sensing;(4)Linear and rotation position sensing.
