General Description:TMR1309 is a digital omnipolar magnetic switch that integrates TMR and CMOS technology in order to provide a magnetically triggered digital switch with high sensitivity, high speed, and ultra-low power consumption. It is designed for use in applications that are both power-critical and performance-demanding. It contains a push-pull half-bridge 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, and CMOS push-pull output. An internal band gap regulator is used to provide a temperature compensated supply voltage for internal circuits, permitting a wide range of supply voltages. The TMR1309draws only 1.5μA resulting in ultra-low power operation. It has fast response, accurate switching points, excellent thermal stability, and immunity to stray field interference. It is available in the SOT23-3 package.


Features and Benefits:(1)Tunneling Magnetoresistance (TMR) Technology;(2)Ultra Low Power Consumption at 1.5μA;(3)High Frequency Response > 1kHz;(4)Operation with North or South Pole;(5)Very Low Switching Points for Ultra High Sensitivity;(6)Compatible with a Wide Range of Supply Voltages;(7)Excellent Thermal Stability;(8)High Tolerance to External Magnetic Field Interference


Applications:(1)Proximity Switches;(2)Position and Speed Sensing;(3)Open/close switch for portable devices
