Power Supply, Reference, and Gain Options
The EVM requires a single power supply in the range of +2.7-V to +5.5-V DC, for proper operation of the
device. The EVM (without a Hall sensor installed) draws less than 10 mA at 5.5 V.
Power can be applied to the EVM via the banana jacks labeled VCC and GND, or through clip leads
directly to the VCC and GND test points. When operating the EVM, TI recommends to use a linear DC
bench supply, current limited to 50 mA.
3.1
Reference Voltage Selection
The EVM provides two jumpers to configure the reference voltage output selection. The reference
selection input pins are pulled to ground, or logic ‘0’ by default (jumpers ‘open’). Closing the jumpers
places the associated REFSEL pin at the applied Vcc potential (logic ‘1’). Table 3 provides a description of
the available options:

Gain Setting and Compensation Frequency
The DRV411EVM provides two jumpers to configure the gain and sensor excitation frequency selection.
The gain selection input pins are pulled to ground, or logic ‘0’ by default (jumpers ‘open’). Closing the
jumpers places the associated GSEL pin at the applied Vcc potential (logic ‘1’). Table 4 provides a
description of the available options:

Excitation/chopping circuitry switched off. The gain and compensation is set by using
external resistors and capacitors (R3/C3 and R4/C4).
EVM Operation
There are four pin sockets on the left side of the EVM for mounting the user-supplied Hall-sensor. Besides
indium antimonide (InSb) Hall elements, the DRV411 can also be connected to symmetrical gallium
arsenide (GaAs) Hall elements such as the HG-302C from AKM Semiconductor.
With a Hall sensor mounted to the DRV411, the user is then free to mount their compensation coil to the
‘drilling area’ noted on the EVM. The area inside the silkscreen is free of any copper and can be used as
needed to provide a means of securing the coil to the EVM. Connectors J1 and J2 are provided to
terminate the compensation coil. Pins 1 and 2 of both J1 and J2 are connected together and then back to
the ICOMP and IAIN pins of the DRV411 (please refer to the DRV411EVM Schematic, for details). The
coil can be terminated at either the J1 or the J2 location, or between J1 and J2, if necessary.
Once the sensor and compensation coil are mounted to the EVM, apply a current limited (50 mA max)
5-V DC source to the banana jacks or test points labeled VCC and GND. The current to be monitored by
the DRV411 can then be applied through the compensation coil primary winding.

laboratory/development environments by technically qualified electronics experts who are familiar with the dangers and application risks
associated with handling electrical mechanical components, systems and subsystems. It should not be used as all or part of a finished end
product.
Your Sole Responsibility and Risk. You acknowledge, represent and agree that:
1.
2.
3.
4.
You have unique knowledge concerning Federal, State and local regulatory requirements (including but not limited to Food and Drug
Administration regulations, if applicable) which relate to your products and which relate to your use (and/or that of your employees,
affiliates, contractors or designees) of the EVM for evaluation, testing and other purposes.
You have full and exclusive responsibility to assure the safety and compliance of your products with all such laws and other applicable
regulatory requirements, and also to assure the safety of any activities to be conducted by you and/or your employees, affiliates,
contractors or designees, using the EVM. Further, you are responsible to assure that any interfaces (electronic and/or mechanical)
between the EVM and any human body are designed with suitable isolation and means to safely limit accessible leakage currents to
minimize the risk of electrical shock hazard.
Since the EVM is not a completed product, it may not meet all applicable regulatory and safety compliance standards (such as UL,
CSA, VDE, CE, RoHS and WEEE) which may normally be associated with similar items. You assume full responsibility to determine
and/or assure compliance with any such standards and related certifications as may be applicable. You will employ reasonable
safeguards to ensure that your use of the EVM will not result in any property damage, injury or death, even if the EVM should fail to
perform as described or expected.
You will take care of proper disposal and recycling of the EVM’s electronic components and packing materials.
Certain Instructions. It is important to operate this EVM within TI’s recommended specifications and environmental considerations per the
user guidelines. Exceeding the specified EVM ratings (including but not limited to input and output voltage, current, power, and
environmental ranges) may cause property damage, personal injury or death. If there are questions concerning these ratings please contact
a TI field representative prior to connecting interface electronics including input power and intended loads. Any loads applied outside of the
specified output range may result in unintended and/or inaccurate operation and/or possible permanent damage to the EVM and/or
interface electronics. Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the
load specification, please contact a TI field representative. During normal operation, some circuit components may have case temperatures
greater than 60°C as long as the input and output are maintained at a normal ambient operating temperature. These components include
but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors which can be identified using the
EVM schematic located in the EVM User's Guide. When placing measurement probes near these devices during normal operation, please
be aware that these devices may be very warm to the touch. As with all electronic evaluation tools, only qualified personnel knowledgeable
in electronic measurement and diagnostics normally found in development environments should use these EVMs.
Agreement to Defend, Indemnify and Hold Harmless. You agree to defend, indemnify and hold TI, its licensors and their representatives
harmless from and against any and all claims, damages, losses, expenses, costs and liabilities (collectively, "Claims") arising out of or in
connection with any use of the EVM that is not in accordance with the terms of the agreement. This obligation shall apply whether Claims
arise under law of tort or contract or any other legal theory, and even if the EVM fails to perform as described or expected.
Safety-Critical or Life-Critical Applications. If you intend to evaluate the components for possible use in safety critical applications (such
as life support) where a failure of the TI product would reasonably be expected to cause severe personal injury or death, such as devices
which are classified as FDA Class III or similar classification, then you must specifically notify TI of such intent and enter into a separate
Assurance and Indemnity Agreement.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
