TMR1155
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 parator 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 pensated supply voltage for internal circuits, permitting a wide range of supply voltages up to 40V. The TMR1155 draws only 0.6m A resulting in low power operation. It has fast response, accurate switching points, excellent thermal stability, and immunity to stray field interference....
