TMR1155
TMR Z-Axis Unipolar Switch
General Description
TMR1155 is a digital unipolar 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 full-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 up to 40V. The TMR1155 draws only 0.6mA 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
SOT23-3 package (P/N TMR1155S) or the TO-92S package (P/N TMR1155T).
