Description | |
The TMR1202D series magnetic switch sensors are bipolar latching magnetic switch sensors that integrate Tunnel Magnetoresistance (TMR) sensors and CMOS circuits. They can convert changing magnetic field signals into digital voltage signals to achieve precise position detection. Unlike Hall or Anisotropic Magnetoresistance (AMR) sensors, TMR sensors have extremely high resistance values. This allows the series of switch sensors to operate in a full-time power supply mode, maintaining low power consumption while achieving true continuous detection of magnetic field signals. This approach avoids the sampling errors that occur with traditional time-division power supply modes. This series of sensors features a static supply current as low as 1.5 μA and maintains a magnetic signal response frequency of 1 kHz. | DFN3L |
