General Description
TMR1306 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 an open-drain output driver. 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 TMR1306 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 SOT23-3 and TO92-3 package.
