General Description：The digital Unipolar magnetic switch TMR1162 delivers nanoampere level power consumption (200nA average current) with high sensitivity, fast response, accurate switching points, excellent thermal stability, and immunity to stray field interference, and it is designed for use in applications which are both power-critical and performance-demanding The TMR1162 integrates a full-bridge TMR magnetic sensor with push-pull structure and the CMOS signal processing circuitry in one package, which include an on-chip TMR voltage generator for precise magnetic sensing, a TMR voltage amplifier and comparator plus a Schmitt trigger. This integrated signal conditioning electronics enable such the feature as switching hysteresis for noise rejection, and push-pull output. With the internal band gap regulator providing a temperature compensated supply voltage, the TMR1162 also enables a wide range of supply voltages. The TMR1162 is available in SOT23-3 (P/N TMR1162S)andTO-92S (P/N TMR1162T) .
