General Description

The TMR1162 is a 200nA ultra-low power magnetic switch sensor. It is a 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 integrates a push-pull half-bridge TMR magnetic sensor and CMOS signal processing circuitry within the same package. Designed for use in applications that are both power-critical and performance-demanding, this device includes an on-chip TMR voltage generator for precise magnetic sensing, TMR voltage amplifier and comparator, a Schmitt trigger to provide switching hysteresis for noise rejection, and open-drain output. An internal band gap regulator is used to provide temperature compensated supply voltage for internal circuits, and it allows a wide range of operating supply voltages. The TMR1162 features ultra-low power consumption at 200nA with a fast internal switching frequency at 50Hz. Other important features include accurate switching points, excellent thermal stability, and a wide range of supply voltages. It is available in two packaging form factors: SOT23-3 (P/N TMR1162S), or TO-92S (P/N TMR1162T).
