Description

The TMR1212 is a bi-stable digital bipolar 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. Compared with conventional magnetic switch sensors, TMR1212 can detect and store the ON/OFF state triggered by magnetic polarity without power supply, and the latest state can be retrieved immediately after power supply is resumed. Designed for use in applications that are power-critical, performance-demanding, and failsafe, 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 CMOS push-pull 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 TMR1212 draws only 1.5μA resulting in ultra-low power operation, additionally it has fast response, accurate switching points, excellent thermal stability, and immunity to stray field interference. TMR1212 is available in two compact SOT23-3 and TO92S packages.
