China Ver. 1.0a TMR BIPOLAR SWITCH MMS1X1H MMS1X1H Ultra-Low Power TMR Bipolar Switch General Description The MMS1X1H is a digital bipolar magnetic s witch that integrates TMR and CMOS technology in order to provide a magnetically triggered digital switch with hig h sensitivity, high speed, and ultra-low power consumption. It integrates a push-pull half-bridge TMR magnetic sensor and CMOS signal processing circuitry within the same package. Designed for use in applications that are both power -critical and performanc e-demanding, this device includes an on -chip TMR voltage generator for precise magnetic sensing, TMR voltage amplifier and comparator, a Schmitt trigger to provide switching hysteresis for noise rejection, and CMOS push-pull output. An internal band gap regulator is used to provide temperature compensated supply voltage for internal circuits , and it allows a wide range of operating supply voltages. The MMS1X1H draws only 1.5μA resulting in ultra-low power operation, additionally it has fast response, accurate switching points , excellent thermal stability, and immunity to stray field interference . It is available in two packaging form factors: SOT23-3 (P/N MMS1X1HS), or TO-92S (P/N MMS1X1HT). Block Diagram Features and Benefits  Tunneling Magnetoresistance (TMR) Technology  Ultra Low Power Consumption at 1.5μA  High Frequency Response up to 1kHz  Bipolar Latching Operation  Low Operate Points for High Sensitivity  Compatible with a Wide Range of Supply V oltages  Excellent Thermal Stability  High Tolerance to External Magnetic Field Interference

Applications

 Utility Meters including Water, Gas, and Heat Meters  Solid State Switches  Speed Sensing  Rotary and Linear Position Sensing

Application Information

Package Information

SOT23-3 package drawing: The output of the MMS1X1H switches low (turns on) when a magnetic field parallel to the TMR sensor exceeds the operate point threshold, B OP. When the magnetic field is reduced below the release point, B RP, the device output goes high (turns off). The difference between the magnetic operate point and release point is the hysteresis BH of the device. It i s strongly recommended that an external bypass capacitor be connected in close proximity to the device between the supply and ground to reduce noise. The typical value of the external capacitor is 0.1μF.
