They are designed to respond to alternating North and South poles. While the magnetic flux density(B) is larger than operate point (Bop), the output will be turned on (Low), the output is held until the magnetic flux density(B) is lower than release point (Brp), then turn off (High). The MT1401 family provides a variety of packages to customers: SOT-23/SOT-89B for surface mount and TO-92 flat for through-hole mount. All packages are RoHS compliant. www.magntek.de Rev.8 12/2014 01/10 MT1401 Series CMOS, Latch, Hall-Effect Magnetic Position Sensors VS Reference Regulator OSC Dynamic offset cancellation ESD ESD Hall element Output ITA COMP Stage GND Functional Block Diagram VOUT Function Description Definition of Magnetic Parameters BOP: Operating Point Magnetic flux density applied on the branded side of the package which turns the output driver ON (VOUT = Low) BRP: Release Point Magnetic flux density applied on the branded side of the package which turns the output driver OFF (VOUT = high) BHYST: Hysteresis Window BOP-BRP Definition of Switching Function Output (V) Output (V) North Pole BOP 0 BRP South Pole Switching Behavior of AT North Pole BRP 0 BOP South Pole Switching Behavior of A, BT and ET www.magntek.de Rev.8 12/2014 02/10 MT1401 Series CMOS, Latch, Hall-Effect Magnetic Position Sensors NS OUT=Low OUT=High Switching Point of AT Motion SN OUT=Low OUT=High Switching Point of A SN SN Motion OUT=Low OUT=High Switching Point of BT Note: Direction of magnetic flux Pin Description MT1401AT Name Number Vs 1 GND 3 Output 2 Description .
