MT8651A

MT865X Omni-polar, Nano Power Hall-Effect Switch IC 1 Product Description The MT865X family is produced with CMOS technology. The Hall IC internally includes high sensitivity horizontal hall plates, sleep/awake logics for mode control, a low-power on-chip oscillator, low noise analog signal chain with dynamic offset cancellation, hysteresis comparators and an output driver. The product responds to either North pole or South pole magnetic fields. The output will be turned on (Low) when the magnetic flux density (B) is larger than the operating point (BOP), and be turned off (High) when the magnetic flux density (B) is lower than the releasing point (BRP). 4 Applications The MT865X family provides a variety of packages to customers: SOT-23-3L for surface mount and flat TO92 for through-hole mount. All packages are RoHS compliant. ￭ ￭ ￭ ￭ ￭ ￭ ￭ 2 Features ￭ ￭ ￭ ￭ ￭ ￭ ￭ ￭ 5.
