The TMAG5123-Q1 is a chopper-stabilized omnipolar,  
active-low Hall-effect switch sensor. The TMAG5123-  
Q1 integrates an in-plane sensor enabling the sensing  
of horizontal fields. Available in the SOT-23 package,  
the TMAG5123-Q1 allows measuring magnetic fields  
that are parallel to the surface of the printed circuit  
board (PCB) to ease mechanical placement.  
Different sensitivity levels are available to match the  
specific requirement of the application. When the  
applied magnetic flux density value exceeds the BOP  
threshold in absolute magnetic field values, the open-  
drain output produces a low-state voltage. The output  
remains low until the applied field decreases to less  
than the BRP threshold also in absolute terms.  
The TMAG5123-Q1 2.7-V to 38-V operating voltage  
range and reverse polarity protection of up to –20-V  
for the device is designed for a wide range of  
industrial and automotive applications.

8 Detailed Description  
8.1 Overview  
The TMAG5123-Q1 device is a chopper-stabilized Hall sensor with a digital omnipolar switch output for magnetic  
sensing applications. The TMAG5123-Q1 device can be powered with a supply voltage range between 2.7-V  
and 38 V, and can withstand –20-V reverse battery conditions continuously. Note that the TMAG5123-Q1 device  
will not operate when approximately –20-V to 2.7-V is applied to the VCC pin (with respect to GND). In addition,  
the device can withstand voltages up to 40 V for transient durations.  
While most of the Hall-effect sensors switch their output in the presence of a vertical field, the TMAG5123-Q1  
will switch the output in the presence of a horizontal field. The TMAG5123-Q1 is then an in-plane or vertical  
sensor, sensitive to a vertical or parallel magnetic fields.  
The omnipolar configuration allows the Hall sensor to respond to either a south or north pole. A strong magnetic  
field of either polarity will cause the output to pull low (operate point, BOP), and a weaker magnetic field will  
cause the output to release (release point, BRP). Hysteresis is included in between the operate and release  
points, so magnetic field noise will not trip the output accidentally.  
An external pullup resistor is required on the OUT pin. The OUT pin can be pulled up to VCC, or to a different  
voltage supply. This allows for easier interfacing with controller circuits.

8.3.2 Device Output  
The TMAG5123-Q1 is featured with an open drain output. In order to generate a two state output, a pull-up  
resistor needs to be added.  
Once the device is powered and with no magnetic field applied to it, the output stays at Vout(H). As an omnipolar  
sensor the output will go down to Vout(L) when the field increase beyond the BOP threshold either with a north  
or a south magnetic field. When the field decrease below the BRP threshold, either with a north or a south  
magnetic field, the output will go up to Vout(H)

8.3.3.1 Load Dump Protection  
The TMAG5123-Q1 device operates at DC VCC conditions up to 38-V nominally, and can additionally withstand  
VCC = 40-V. No current-limiting series resistor is required for this protection.  
8.3.3.2 Reverse Supply Protection  
The TMAG5123-Q1 device is protected in the event that the VCC pin and the GND pin are reversed (up to –20-  
V).

8.3.5 Power-On Time  
Figure 8-5 shows the behavior of the device after the VCC voltage is applied and when the field is below the BOP  
threshold. Once the minimum value for VCC is reached, the TMAG5123-Q1 will take time tON to power up and  
then time tPD to update the output to a level High.  
Figure 8-6 shows the behavior of the device after the VCC voltage is applied and when the field is above the BOP  
threshold. Once the minimum value for VCC is reached, the TMAG5123-Q1 will take time tON to power up and  
then time tPD to update the output to a level High  
In both case the output value during tON is unknown. The output value during tPD will be set at high.

8.3.6 Propagation Delay  
The TMAG5123-Q1 samples the Hall element at a nominal sampling interval of tPD to detect the presence of a  
magnetic south or north pole. Between each sampling interval, the device calculates the average magnetic field  
applied to the device. If this average value crosses the B OP or B RP threshold, the device changes the  
corresponding level as defined in Figure 8-3. The Hall sensor + magnet system is by nature asynchronous,

therefore the propagation delay (tPD) will vary depending on when the magnetic field goes above the BOP value.  
As shown in Figure 8-7, the output delay also depends on when the magnetic field goes above the BOP value.  
The first graph in Figure 8-7 shows the typical case. The magnetic field goes above the BOP value at the moment  
the output is updated. The part will only require one sampling period of tPD to update the output.  
The second graph in Figure 8-7 shows a magnetic field going above the B OP value just before half of the  
sampling period. This is the best-case scenario where the output is updated in just half of the sampling period.  
Finally, the third graph in Figure 8-7 shows the worst-case scenario where the magnetic field goes above the B  
value just after half of the sampling period. At the next output update, the device will still see the magnetic  
OP  
field under the BOP threshold and will require a whole new sampling period to update the output.

Figure 8-7. Field Sampling Timing  
Figure 8-8 shows TMAG5123-Q1 propagation delay analysis when a magnetic south or north pole is applied.  
The Hall element of the TMAG5123-Q1 experiences an increasing magnetic field as a magnetic south or north  
pole approaches the device, as well as a decreasing magnetic field as a magnetic south or north pole moves  
away. At time t1, the magnetic field goes above the BOP threshold. The output will then start to move after the  
propagation delay (tPD). This time will vary depending on when the sampling period is, as shown in Figure 8-7. At  
t2, the output start pulling the output voltage Low. At t3, the output is completely pulled down. The same process  
happens on the other way when the magnetic value is going under the BRP threshold.

8.3.7 Chopper Stabilization  
The Basic Hall-effect sensor consists of four terminals where a current is injected through two opposite terminals  
and a voltage is measured through the other opposite terminals. The voltage measured is proportional to the  
current injected and the magnetic field measured. By knowing the current inject, the device can then know the  
magnetic field strength. The problem is that the voltage generated is small in amplitude while the offset voltage  
generated is more significant. To create a precise sensor, the offset voltage must be minimized.  
Chopper stabilization is one way to significantly minimize this offset. It is achieved by "spinning" the sensor and  
sequentially applying the bias current and measuring the voltage for each pair of terminals. This means that a  
measurement is completed once the spinning cycle is completed. The full cycle is completed after sixteen  
measurements. The output of the sensor is connected to an amplifier and an integrator that will accumulate and  
filter out a voltage proportional to the magnetic field present. Finally, a comparator will switch the output if the  
voltage reaches either the BOP or BRP threshold (depending on which state the output voltage was previously  
in).  
The frequency of each individual measurement is referred as the Chopping frequency, or f CHOP. The total  
conversion time is referred as the Propagation delay time, tPD, and is basically equal to 16/fCHOP. Finally, the  
Signal bandwidth, f BW, represents the maximum value of the magnetic field frequency, and is equal to (f  
CHOP/16)/2 as defined by the sampling theorem.

9 Application and Implementation  
Note  
Information in the following applications sections is not part of the TI component specification, and TI  
does not warrant its accuracy or completeness. TI’s customers are responsible for determining  
suitability of components for their purposes. Customers should validate and test their design  
implementation to confirm system functionality.  
9.1 Application Information  
The TMAG5123-Q1 is typically used in magnetic-field sensing applications to detect the proximity of a magnet  
that is in the "in-plane" axis from the sensor. The magnet is often attached to a movable component in the  
system.  
The TMAG5123-Q1 is a Hall sensor that implements a Hall sensing element that senses parallel to the package  
of the part rather than through the z-axis of the device. This eases constraints in system design where a parallel  
magnetic field is needed to be detected, but normal industry packages, such as TO-92 are undesirable due to  
space constraints.

9.2.1.2 Detailed Design Procedure  
When designing a digital-switch magnetic sensing system, three variables should always be considered: the  
magnet, sensing distance, and threshold of the sensor.  
The TMAG5123-Q1 device has a detection threshold specified by parameter B OP, which is the amount of  
magnetic flux required to pass through the Hall sensor mounted inside the TMAG5123-Q1. To reliably activate  
the sensor, the magnet must apply a flux greater than the maximum specified BOP. In such a system, the sensor  
typically detects the magnet before it has moved to the closest position, but designing to the maximum  
parameter ensures robust turn-on for all possible values of BOP. When the magnet moves away from the sensor,  
it must apply less than the minimum specified BRP to reliably release the sensor.  
Magnets are made from various ferromagnetic materials that have tradeoffs in cost, drift with temperature,  
absolute maximum temperature ratings, remanence or residual induction (Br), and coercivity (Hc). The Br and the  
dimensions of a magnet determine the magnetic flux density (B) it produces in 3-dimensional space. For simple  
magnet shapes, such as rectangular blocks and cylinders, there are simple equations that solve B at a given  
distance centered with the magnet.

An online tool, the Hall Effect Switch Magnetic Field Calculator, that uses these formulas is located at http://  
www.ti.com/product/tmag5123-Q1.  
All magnetic materials generally have a lower B r at higher temperatures. Systems should have margin to  
account for this, as well as for mechanical tolerances.  
For the TMAG5123B-Q1, the maximum BOP is 4.5 mT. Choosing a 1-cm cube NdFeB N45 magnet, Equation 1  
shows that this point occurs at 3.05 cm. This means that, provided the design places the magnet within 3.05 cm  
from the sensor during a "turn-on" event, the magnet will activate the sensor. The removal of the magnet away  
from the device will ensure a crossing of the minimum BRP point and will return the device to its initial state.

10 Power Supply Recommendations  
The TMAG5123-Q1 is powered from 2.7-V to 38-V DC power supplies. A decoupling capacitor close to the  
device must be used to provide local energy with minimal inductance. TI recommends using a ceramic capacitor  
with a value of at least 0.01 µF.  
11 Layout  
11.1 Layout Guidelines  
The bypass capacitor should be placed near the TMAG5123-Q1 to reduce noise.  
Generally, using PCB copper planes underneath the TMAG5123-Q1 device has no effect on magnetic flux, and  
does not interfere with device performance. This is because copper is not a ferromagnetic material. However, If  
nearby system components contain iron or nickel, they may redirect magnetic flux in unpredictable ways.
