MT8691A

MT869X Uni-polar, Nano Power Hall-Effect Switch IC 1 Product Description The MT869X 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 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 MT869X family provides a variety of packages to customers: DFN & SOT-23 for surface mount and flat TO-92 for through-hole mount. All packages are RoHS compliant. 2 Features Out GND SOT-23 1 2 3 Flat TO-92 1 3 2 DFN1608 1 2 3 DFN1616 4 5 2 Description Power Output Ground SOT-23 Top-View OUT OUT Vcc Vcc 5 54 4 1 3 NCNC GND NC 2 2 GND NC 按钮 OUT 13 OUT 2 1 3 2 GND TO-92 Top-View OUT 3 3 GND 2 2 Vcc 1 1 OUT GND Vcc Figure.1 magntek.com.cn | Magnetic Tech Makes Magic Change Vcc OUT MT8691DT-1616 3 MT8691DT-1608 DFN1608 Top-View TO-92 Top-View SOT-23, tape & reel (3000pcs/bag) DFN1608, tape & reel (10000pcs/bag) DFN1616, tape & reel (3000pcs/bag) SOT-553 Top-View SOT-553 Top-View GND MT8691AT Vcc Flat TO-92, bulk packaging (1000pcs/bag) 2 1 MT8691A Vcc Description 1 Part No. 3 3 Product Overview of MT869X Push Pull SOT-23 Top-View GND ￭ VCC 按钮 ￭ ￭ 5.
