MT6131AT

MT613X Omni-polar, Low Power, 360 Degree Switch IC 1 Product Description The MT613X family is produced with monolithic technology，which builds AMR sensor & ASIC on one chip. The IC internally includes a Wheatstone bridge with magnetic film, a current regulator for operating with supply voltage from 1.65V to 5.0V, a sleep/awake logic for low power consumption requirement, small signal amplifier and Schmitt trigger comparator with dynamic offset cancellation, and an output driver with push pull output. When combined with a magnet, it becomes a noncontact switch with low power consumption, high sensitivity and high reliability. All directions of horizontal magnetic field parallel to the electrode of the package can be detected by an arbitrary polarity. 4 Application The MT613X family provide SOT-23 for surface mount， RoHS compliant. 2 Features ￭ ￭ ￭ ￭ ￭ ￭ ￭ ￭ ￭ Home appliances, Industrial Position Detection Proximity Switch Smart Meter Speed Detection Handheld Device Consumer Device 5.

To operate the MR switch, the magnetic field should be applied to the sensor parallel to the package. MT613X series detect the magnetic field in any parallel direction, but it does not respond to magnetic field in the vertical direction.
