  • TMR1302B

General Description:The TMR1302B 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 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 performance-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 TMR1302B 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 TMR1302BS), or TO-92S (P/N TMR1302BT).

 

Features and Benefits:(1)Tunneling Magnetoresistance (TMR) Technology;(2)Ultra Low Power Consumption at 1.5μA;(3)High Frequency Response at 1kHz;(4)Operation with North or South Pole;(5)Low Operate Points for 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)Utility Meters including Water, Gas, and Heat Meters;(2)Proximity Switches;(3)Speed Sensing;(4)Rotary and Linear Position Sensing.
