MT6111AT

MT611X Omni-polar, Low Power AMR Switch IC 1 Product Description The MT611X family is produced with monolithic technology. Which built AMR sensor & ASIC on one chip. The IC internally includes a Wheatstone bridge with magnetic film, a voltage regulator for operating with supply voltage from 1.8V to 5.5V, 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 open-drain output. When combined with a magnet, it becomes a noncontact switch with low power consumption, high sensitivity and high reliability. A horizontal magnetic field parallel to the electrode of the package can be detected by an arbitrary polarity. 4 Application The MT611X family provides a variety of packages to customers: SOT-23 for surface mount and flat TO-92 for through-hole mount. All packages are RoHS compliant. ￭ ￭ ￭ ￭ ￭ ￭ ￭ 2 Features ￭ ￭ ￭ ￭ ￭ ￭ ￭ ￭ ￭ 5.
