MT6341 Datasheet | MagnTek

Description The MT634X 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 parator with dynamic offset cancellation, and an output driver with push-pull output. When bined with a magnet, it bees 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. The MT634X family provides a variety of packages to customers: SOT-23 for surface mount and flat TO-92 for through-hole mount. All packages are Ro HS pliant. 2 Features ￭ Monolithic Technology ￭ AMR (Anisotropic Magneto Resistance) ￭ Omni-polar Switch ￭ 1.8～5.5V Operating Vcc Range ￭ -40℃~125℃ Operating Temperature ￭ Package Option: SOT-23 / Flat TO-92 ￭ Magnetic Sensitivity Option: MT6341 （BOP=±10Gs, BRP=±8Gs） MT6343 （BOP=±18Gs, BRP=±15Gs） ￭ Pull-push Output ￭ Low Power Consumption: Average Supply Current =1.3u A (Typ) ￭ Ro HS pliant: (EU)2015/863 4 Applications ￭ Home appliances, Industrial ￭ Position Detection ￭ Proximity Switch ￭ Smart Meter ￭ Speed Detection ￭ Handheld Device ￭ Consumer Device 5.
