e magnetic sensitivity transfer curve illustrates the characteristic behavior of an analog TMR sensor’s resistance change as the strength of
an applied magnetic eld changes. e magnet approach curve (red line) shows the change in resistance as the strength of an applied mag-
netic eld increases. e magnet recede curve (blue dashed line) shows the change in resistance as the strength of an applied magnetic eld
decreases. Alternatively, you can think of the resistance going down the red slope as a magnet approaches the sensor, and going up the blue
dashed slope as the magnet moves further away from the sensor.

With the open drain output, the system voltage can

. Please keep in mind the supply
voltage to the RR130 must remain at 3.6V. A decou-
pling capacitor between the supply voltage and ground
is required with placement close to the magnetic sensor.
A typical capacitor value of 0.1 mF will suce.
RR120 Digital Output
Application Circuit
e output voltage on the RR120 is active
low, meaning that while a suciently
strong magnetic eld is present, the output
voltage is low. e output voltage can be
connected to a digital I/O pin on a micro-
controller. A decoupling capacitor between
the supply voltage and ground is required
with placement close to the magnetic
sensor. A typical capacitor value of 0.1 mF
will suce.
RR110 Magnetoresistance
Application Circuit
e RR110 can be congured with a
constant voltage source and a xed resistor
to create a voltage divider circuit. Alterna-
tively, a constant current source eliminates
the need for a xed resistor.

TMR TECHNICAL & APPLICATIONS INFORMATION
GLOSSARY OF TERMS
Hysteresis:
Hysteresis refers to the dierence between two points
of interest for a particular device. For digital sensors and switches,
it represents the dierence between the operate sensitivity and the
release sensitivity, expressed either as an absolute value (B
OP
– B
RP
) or
the % dierence (B
OP
– B
RP
)/B
OP
. For an analog sensor, the hyster-
esis is the dierence between the “magnet approach curve” and the
“magnet recede curve.”
Magnet Approach Curve:
e magnet approach curve is the
characteristic change in resistance of an analog TMR sensor as an
applied magnetic eld approaches the sensor, typically plotted as a
function of the magnetic eld strength.
Magnet Recede Curve:
e magnet recede curve is the charac-
teristic change in resistance of an analog TMR sensor as an applied
magnetic eld recedes from the sensor, typically plotted as a function
of the magnetic eld strength.
Magnetoresistance:
Magnetoresistance is a phenomenon
wherein the electrical resistance of certain materials changes when
exposed to an externally-applied magnetic eld.
Magnetic Transfer Curve:
e magnetic transfer curve denes
the characteristic behavior of an analog TMR sensor by combin-
ing both the magnet approach curve and the magnet receive curve
together.
Magnetic Tunnel Junction:
A magnetic tunnel junction is a
thin lm structure consisting of two magnetic layers separated by a
thin insulator. Because the insulating layer is thin enough (typically
a few nanometers), electrons can tunnel from one magnetic layer into
the other.
Operate Sensitivity:
e operate sensitivity denes the upper
limit of the strength of an applied magnetic eld that a digital TMR
sensor or switch must operate.
Operate Time:
e operate time is the dierence, in time,
between the application of a magnetic eld and the output response
of the device. In an analog sensor, the response is a change in output
resistance. In a digital sensor, the response is a change in state of the
electrical output.
Release Sensitivity:
e release sensitivity denes the lower
limit of the strength of an applied magnetic eld that a digital TMR
sensor or switch must release.
Release Time:
e release time is the dierence, in time, between
the removal of an applied magnetic eld and the output response of
the device. In an analog sensor, the response is a change in output
resistance. In a digital sensor, the response is a change in state of the
electrical output.
Tunnel Magnetoresistance (TMR):
Tunnel Magnetoresis-
tance is the magnetoresistive eect that occurs in a magnetic tunnel
junction.

Magnetic sensitivity maps show the operate and release loci in three-
dimensional space when a magnet is presented to a magnetically
operated switch or sensor. e absolute operate and release distances
between the magnet and the sensor will vary depending on the sen-
sitivity of the switch and the strength of the magnet. However, the
shape and direction of the operate loci stay relatively constant except
for cases where the magnet is physically much larger than the sensor.
ese plots were generated using a 2mm^3 cubic shaped NdFeB N52
magnet with its North pole presented to the ground pin and a South
pole presented to the opposite side.
