Description
TMR1305 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-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 TMR1305 draws only 2 μA resulting in ultra-low power operation. It has fast response, accurate switching points, excellent thermal stability, and immunity to stray field interference. TMR1305 is available in two compact SOT23-3 and TO92S packages.
SOT23-3 TO92S
Features and Benefits
Tunneling magnetoresistance (TMR) technology Ultra low power consumption at 2 μA High frequency response > 1 kHz Operation with north or south pole Compatible with a wide range of supply voltages Low switching points for high sensitivity High tolerance to external magnetic field interference Excellent temperature stability RoHS & REACH compliant
Applications
Utility meters: water, gas, and heat meters Proximity switches Position and speed sensing Motor and fan control
