MT9105ET

MT910X Ratiometric Linear Hall-Effect IC, Analog Output 1 Product Description The MT910X device is a linear Hall effect IC that responds proportionally to magnetic flux density. The device can be used for accurate position sensing in a wide range of applications. The device operates from 3.0V to 5.5V power supplies. When no magnetic field is present, the analog output drives ½ of VCC. The output changes linearly with the applied magnetic flux density, and four sensitivity options enable maximal output voltage swing based on the required sensing range. North and south magnetic poles produce unique voltages. The MT910X family provides a variety of packages to customers. SOT-23 (Thin Outline) for surface mount and flat TO-92 for through-hole mount. All packages are RoHS compliant. 2 Features ￭ ￭ ￭ ￭ ￭ ￭ ￭ BCD Technology Factory-programmed Ratiometric Rail to Rail Analog Output Low-Noise Output 3.0~5.5V Operating Vcc Range -40℃~150℃ Operating Temperature Package Option: Flat TO-92 SOT-23 (Thin Outline) ￭ Magnetic Sensitivity Option: 1.50mV/Gs MT9101 Series @Vcc = 5V 2.50mV/Gs MT9102 Series @Vcc = 5V 3.40mV/Gs MT9103 Series @Vcc = 5V 5.00mV/Gs MT9105 Series @Vcc = 5V 1.00mV/Gs MT9101 Series @Vcc = 3.3V 1.60mV/Gs MT9102 Series @Vcc = 3.3V 2.15mV/Gs MT9103 Series @Vcc = 3.3V 3.15mV/Gs MT9105 Series @Vcc = 3.3V ￭ RoHS Compliant: (EU)2015/863 4 Applications ￭ ￭ ￭ ￭ ￭ ￭ ￭ ￭ Home appliances Industrial Speed Detection Position Detection Magnetic Encoder Ferrous Metal Sensing Vibration Sensing Weight Sensing 5.
