TMR1303
TMR Omnipolar Switch
General Description
TMR1303 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 TMR1303 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 , TO92S and LGA3L 2x1.5x0.63 package.
