Always use electrical safety precautions to help ensure your personal safety and those working around you. Contact TI's Product Information Center http:// support/ti./com for further information. Save all warnings and instructions for future reference. WARNING Failure to follow warnings and instructions may result in personal injury, property damage or death due to electrical shock and burn hazards. The term TI HV EVM refers to an electronic device typically provided as an open-framed, unenclosed printedcircuit board assembly. It is intended strictly for use in development laboratory environments, solely for qualified professional users having training, expertise, and knowledge of electrical safety risks in development and application of high-voltage electrical circuits. Any other use and/or application are strictly prohibited by Texas Instruments. If you are not suitable-qualified, you should immediately stop from further use of the HV EVM. 1. Work Area Safety a. Keep work area clean and orderly. b. Qualified observer(s) must be present anytime circuits are energized. c. Effective barriers and signage must be present in the area where the TI HV EVM and its interface electronics are energized, indicating operation of accessible high voltages may be present, for the purpose of protecting inadvertent access. d. All interface circuits, power supplies, evaluation modules, instruments, meters, scopes and other related apparatus used in a development environment exceeding 50Vrms/75VDC must be electrically located within a protected Emergency Power Off EPO protected power strip. e. Use stable and nonconductive work surface. f. Use adequately insulated clamps and wires to attach measurement probes and instruments. No freehand testing whenever possible. 2. Electrical Safety As a precautionary measure, it is always a good engineering practice to assume that the entire EVM may have fully accessible and active high voltages. a. De-energize the TI HV EVM and all its inputs, outputs, and electrical loads before performing any electrical or other diagnostic measurements. Revalidate that TI HV EVM power has been safely deenergized. b. With the EVM confirmed de-energized, proceed with required electrical circuit configurations, wiring, measurement equipment connection, and other application needs, while still assuming the EVM circuit and measuring instruments are electrically live. c. After EVM readiness is complete, energize the EVM as intended. WARNING While the EVM is energized, never touch the EVM or its electrical circuits, as they could be at high voltages capable of causing electrical shock hazard.

Wear personal protective equipment (for example, latex gloves or safety glasses with side shields) or protect the EVM in an adequate lucent plastic box with interlocks to protect from accidental touch. Limitation for safe use: EVMs are not to be used as all or part of a production unit. 2 Overview The INA4290 device is a voltage-output, high-side quad-channel current sense amplifier in a QFN (16) package. As shown in INA4290 Gain Option Summary, the INA4290 has gains that range from 20 V/V to 500 V/V, depending on the gain option that is selected. The voltage developed across the device inputs is amplified by the corresponding gain of the specific device, and is presented at the output pin. The device can accurately sense voltage drops across shunts at 2.7-V to +120-V common-mode voltages, dependent of supply voltages. The device survives common-mode voltages from –20 V to +122 V. The device operates with supply voltages between 2.7 V and 20 V, and draws a typical of 320 µA per channel at room temperature. Table 2-1.

The fixture layout is not intended to be a model for the target circuit, nor is it laid out for electromagnetic compatibility (EMC) testing. The INA4290EVM is one PCB with five optional PCB cutouts the engineer can use to test each of the five gain options (1 to 5) listed in INA4290 Gain Option Summary. Each PCB cutout has one INA4290An device (where n is 1, 2, 3, 4, or 5), test points and sockets for external hardware connections, and pads to solder down optional circuitry. 3.1 Features The INA4290EVM PCB provides the following features: • • • • Evaluation of all gain options through provided device boards Ease of access to device pins with test points Pads and sockets for optional filtering at the input pins and output pin Multiple input signal options, including a method to solder a shunt resistor (2512) and safely measure current up to 5 A. See the INAx290 2.7-V to 120-V, 1.1-MHz, Ultra-Precise Current Sense Amplifier Data Sheet for comprehensive information about the INA4290 and the available gain options. SBOU258 – MARCH 2021 Submit Document Feedback INA4290 Evaluation Module Copyright © 2021 Texas Instruments Incorporated 5 Operation www.ti.com 4 Operation 4.1 Quick Start Setup Follow these procedures to set up and use one of the INA4290EVM panels. For these instructions, n is gain option 1, 2, 3, 4, or 5 and x is the channel option 1, 2, 3, or 4. 1. Choose the desired gain option panel variation. 2. Connect an external DC supply voltage (between 2.7 V and 20 V) to a VS test point. Connect the ground reference of that supply to a GND test point on the same panel. 3. Provide a differential input voltage signal to the In+ and In– nodes by connecting the signal leads to the Jx_n pin 1 and Jx_n pin 2 for channel x on the EVM, as explained in Measurements. The INA4290 is a unidirectional current-sensing device because there is no reference pin. The device can only measure current in one direction. 4.2 Measurements The user can either emulate the voltage developed across a sense resistor based on a given set of system conditions with the INA4290EVM, or connect the device inputs to an external shunt. The user can also solder a surface-mount technology (SMT) shunt resistor across the In+ and In– pads, and these inputs can be connected in series with the external system and load. In+ and In- will refer the input of either channel being measured. Jx_n for channel x and Jx_n for channel x. Also shunt resistor is R1_n for channel 1, R5_n for channel 2, R9_n for channel 3, and R13_n for channel 4 will be refered to as Rshunt. To configure a measurement evaluation without a shunt resistor, follow this procedure: 1. Connect a positive differential voltage across the In+ and In– tab. Given the internal GND reference of the device, make sure that the In+ pin is the more positive of the two inputs. Note the In+ and In- are not in the same location on each connector. Use marking on the board to see which pin is In+ and In-. 2. Connect a 2.7-V to 120-V common-mode voltage to the inputs if the differential voltage supply is a floating supply. Connect the positive lead of the external voltage source to the In– tab and source ground to a GND test point. The minimum common-mode voltage should be >VS. This action effectively raises the absolute common-mode voltage of the input pins, while still retaining a positive input differential signal. 3. Measure the output voltage at the Vout test point with respect to GND. To configure a measurement evaluation with a shunt resistor, follow this procedure: 1. Solder a 2512 resistor at the Rshunt pads that connects the In+ and In– inputs. 2. Connect the In+ and In– tabs in series with the load and bus voltage sources while powered off. WARNING Make sure that the equipment (shunt resistor, wires, connectors, and so on) can support the amperage and power dissipation first before you measure the current. Also make sure that the current flowing through Jx does not exceed 5 A. Failure to do so can result in hot surfaces (> 55 °C), damage to the EVM, or personal injury. 3. Power on the system and measure the output voltage at the Vout test point for the correct channel. Vout is equal to the gain of the device multiplied by the differential voltage measured directly at the device input pins. 6 INA4290 Evaluation Module SBOU258 – MARCH 2021 Submit Document Feedback Copyright © 2021 Texas Instruments Incorporated www.ti.com EVM Components 5 EVM Components This section summarizes the INA4290EVM components. For these instructions, n is gain option 1, 2, 3, 4, or 5. 5.1 R2_n, R3_n, R4_n, R6_n, R7_n, R8_n, R10_n, R11_n, R14_n, R15_n, C2_n - C9_n R2_n, R3_n, R4_n, R6_n, R7_n, R8_n are factory-installed 0-Ω 0603 resistors. C2_n - C9_n are not populated. Collectively, these pads allow user-defined filters for the input pins (IN+ and IN–) and the output pin (OUT) of the INA4290. If a filter is desired, remove these resistors and replace them with > 0-Ω SMT resistors and populate the capacitor pads with capacitors. Consider the input bias current of the device when using input filtering. 5.2 C1_An C1_An is a 0.1-µF, power-supply bypass capacitor. 5.3 R1_n, R5_n, R9_n, R13_n(Rshunt) Rshunt is unpopulated, but allows the user to solder down a surface-mount shunt resistor between the In+ and In– pads sensed by IN+ and IN– input pins. If used, make sure Rshunt has proper power dissipation for the selected current load and below 5 A. The chosen resistor must have a 2512 footprint. 5.4 U1_n (INA4290) U1_An is the location for the INA4290An test device. Consider these factors when selecting the appropriate device gain: • • • • The differential input voltage is either applied across the inputs or developed based on the load current that flows through the shunt resistor. Make sure that the output voltage does not exceed the supply voltage. This limiting factor requires attention to device selection. The selected device must allow the output voltage to remain within the acceptable range after the developed input voltage is amplified by the respective device gain. The output voltage must remain within the devicespecified swing limitations for response in the linear range. An output below the minimum allowable output requires a device with a higher gain. Likewise, an output above the maximum allowable output requires a device with a lower gain.
