Datasheet LF2117XTMR Series
TMR Omnipolar Switch 160nA Push Pull Sensor
Pin Configuration and Sensing Direction of Magnetic Field Part Marking Code:
Ixxxy: I = LF21173TMR; xxx = Julian manufactured date; y = manufactured year Moisture Sensitivity Level: Rating is 3 Pick and Place Nozzle: Samsung CN140 or equivalent
Pin Name Pin No. LGA4 Pin Function
V 3 Output out GND 4 Ground V 2 Supply Voltage cc DNC 1 Do Not Connect
Part Numbering System LF - x - x - x - x - x TMR Littelfuse Brand Tunneling Magnetoresistance Switch Type Technology Sensor
Type 1 = Linear Sensor 2 = Omnipolar 3 = Unipolar
Sensitivity Gauss
1 = 5 Gauss 6 = 25 Gauss
Output
2 = 7 Gauss 7 = 35 Gauss 1 = PushPull 3 = 10 Gauss 2 = Open Drain 4 = 14 Gauss 5 = 17 Gauss
Quiescent Current
1 = 200nA
Sensitivity Axis/Package
2 = 1.5uA 1 = X/SOT23 6 = Z/TO92 3 = 0.6mA 2 = Y/SOT23 7 = X/LGA 3 = Z/SOT23 8 = Y/LGA 4 = X/TO92 9 = Z/LGA 5 = Y/TO92
Example:
LF11115 is Bipolar, Push Pull, 200nA, X axis, 17Gauss
