MultiDimension Technology Co., Ltd. Omnipolar Magnetic Switch TMR1308

TMR1308 is a digital omni polar 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-demandin g. 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 TMR1308 draws 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: Tunneling Magnetoresistance (TMR) Technology Ultra Low Power Consumption at 1.5μA High Frequency Response > 1kHz Operation with North or South Pole Very Low Switching Points for Ultra High Sensitivity Compatible with a Wide Range of Supply Voltages Excellent Thermal Stability High Tolerance to External Magnetic Field Interference Applications: Utility Meters including Water, Gas, and Heat Meters Proximity Switches Position and Speed Sensing Motor and Fan Control
