LMP8480 / 81 EVM User’s Guide
1. Introduction
The Texas Instruments LMP8480/81 evaluation module (EVM) helps designers quickly evaluate the
operation and performance of the LMP8480/81 76V Precision High Side Current Sense Amplifiers. The EVM
is ready to connect to power, load, and test instruments through the use of on-board terminals.
Figure 1: Picture of Evaluation Board (LMP8480 version)
The EVM contains one LMP8480 or LMP8481 high side evaluation circuit. The EVM’s come pre-assembled
with the LMP8480/81 device, 0.1Ω sense resistor; bypass capacitor and connection terminals installed. The
Bi-Directional EVM’s include the JP1 and JP2 reference jumpers and terminals.

Setup
3. Board Connections and Components
This section describes the jumpers and connectors on the EVM as well and how to properly connect, set up
the EVM board.
3.1. General Safety Precautions
Connections with 48V or 1A and above should be securely soldered to the terminals to prevent inadvertent
disconnection. Voltages above 70V must be soldered. Clip-on leads are not recommended at high voltages.
Follow all standard high voltage precautions.
All power should be removed when changing connections, even in the low voltage sections. The use of handheld probes while powered is not recommended. Connections should be hard wired.
3.2. Power Supply Input - VCC
The device power supply is connected to the VCC and GND pins. Positions for 4.7uF (optional) and 0.1uF
ceramic bypass capacitors are provided on the VCC lines. Note that these capacitors should be rated for
100V or more. EVM supply voltage is limited to 75V max.
3.3. Current Sense Resistor and Sense Terminals - RSP and RSN
The large current sense resistor pads allow for multiple mounting configurations of both through-hole and
surface mount resistors.
WARNING: The area around the sense resistor can get warm. Use caution when handling or probing.
Figure 2: Rsense Terminals
These pads are bare copper to allow for mounting of any size or shape of resistor, as well as providing heat
dissipation. The larger inner holes are for optional pin socket receptacles (see Bill of Materials) to allow easy
swapping of through-hole resistors for prototyping.
Customer provided sense resistor power dissipation should be limited to less than 1W. The TI supplied 0.1
Ohm resistor power dissipation must be less than 0.5W. Currents higher than 5A should be soldered directly
to the sense pads. Currents above 10A should use an off-board shunt resistor with its own heat sink.
For off-board current sense resistors, the sense lines can be connected to the SENSE+ and SENSE- turret
terminals (with on-board sense resistor removed). It is recommended that these wires be twisted to prevent
noise pickup and to provide some EMI rejection.

LMP8480/81 User’s Guide

Setup
For 4-wire, or “Kelvin” resistors, Figure 2 shows how the sense traces can be cut with an E-Xacto knife to
attach to the “sense” terminals on a 4-Wire surface mount resistor.
Figure 3: Cutting pads to accommodate 4-wire resistors
Load ground currents should be kept off the board. Load current should be returned directly to the power
supply terminals and not through the demo board grounds.
3.4. Optional Input Filtering
The optional Rt+ and Rt- resistor pads are provided to add, in conjunction with C3, C4 and C5, EMI/Noise
filtering to the input. These can be series resistors or inductors. To maintain a continuous solid copper path,
the Rt pads have shorting traces across them. To use these pads, the shorting traces must be be cut before
installing Rt.
Figure 4: Rt shorting traces must be cut before use
To maintain accuracy, these resistors should be of equal value and well matched, as they are in series with
the device’s internal thin-film resistors and will effect the Gain, CMRR and gain accuracy specifications. The
values of these resistors should not exceed a few hundred ohms, and should be kept as low as possible.
Figure 5: Optional Input Filtering Capacitors
Pads C3, C4 and C5 are provided for optional EMI rejection. For RF/EMI protection, values in the 10 to
100pF range are recommended. For lower frequencies, a lowpass filter can be formed with the Rt series
input resistors.

Reference Inputs (Bi-Directional Devices Only)
For Bi-Directional devices, the “zero” output level can be set by a voltage applied to the reference pins. The
reference voltages may be applied externally through the VREF pin, or sourced from the VCC line. These
jumpers will have no effect on devices without reference pins!!!
C6 and C7 are available if reference line bypassing or filtering is desired.

3.6. Output - VOUT
Similar to the Rt resistors, Riso is available for output isolation when driving capacitive loads or for output
short circuit protection. If the output must drive large capacitive loads (like a coax cable), Riso may be
needed to prevent oscillations. The jumper trace between the pads must be cut to use Riso.

3.7. Input VSENSE Test Point – TP1
TP1 allows for the monitoring of the VSENSE voltage through a standard 0.1” header. TP2 provides a
convenient ground if needed. The meters terminals need to be “floating” (not grounded) and will be at the
common mode voltage (Vsource) potential.
3.8.
DUT Mounting Options
For applications where the DUT must be swapped-out, mounting holes are provided for a reusable “Rainbow
Clamp” socket from Rainbow Labs (See Bill of Materials). Otherwise, the DUT may be soldered directly to the
pads.

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
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
