TMR1212
Bi-stable TMR Bipolar Magnetic Switch with Passive Memory Effect
General 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.
