Datasheet V1.0a TMR2301 3 axis TMR linear sensor General Description The 3-Axis TMR2301 linear sensor utilizes three unique push -pull Wheatstone bridges. The 3 -Axis TMR2301 is available in a 4 mm X 4mm X 2.5 mm LGA package. Features and Benefits  Tunneling Magneto resistance (TMR) Technology  Triple-axis Linear Detection  Very Wide Dynamic Range  Low Power Consumption  Excellent Thermal Stability  Compatible with wide Range of Supply Voltages  No need for set/reset calibration

Applications

 Three Orthogonal Direction Sensing  Weak Magnetic Field Sensing  Current Sensors  Position and Displancement Sensing TMR2301 Transfer Curve The following figure shows the response of the 3-axis TMR2301 to an applied magnetic field in the range of ±100 Oe (left) and ±500 Oe when the 3-axis TMR2301 is biased at 1V.
