The TMR1367 is a digital omnipolar magnetic switch that integrates magnetoresistance and CMOS circuitry, which is able to detect the change of magnetic field and output high and low voltage signals for high accuracy position detection.

It contains a full-bridge push-pull tunneling magnetoresistance (TMR) sensor and CMOS signal processing circuitry within the same package, including an on-chip voltage generator and voltage amplifier and comparator for precise magnetic sensing, 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 TMR1367 operates in low voltage and draws only nA resulting in low power operation. It has fast response, accurate switching points, excellent thermal stability, and immunity to stray field interference. It is available in the compact LGA4L (2mm × 1.5mm × 0.63mm) package.
