Product details
Overview
INA4230EVM from Texas Instruments is an evaluation module designed to validate the performance of the INA4230 quad-channel 16-bit digital current monitor IC. It supports up to 10A per channel current measurement via onboard or external shunt resistors, features I²C/SMBus interface compatibility (1.2V–5V bus voltage), and integrates with the TI Sensor Control Board (SCB) and web-based GUI for real-time register access, data logging, and calibration setup.
For engineers reviewing the INA4230EVM datasheet, INA4230EVM pinout, INA4230EVM application, or INA4230EVM equivalent, this module enables rapid validation of high-accuracy current, voltage, power, and energy monitoring in industrial power supplies, server VRMs, battery management systems, and programmable load applications - with full support for shunt configuration, alert thresholding, and multi-EVM synchronization.
Technical Context
The INA4230EVM implements a dedicated hardware platform centered on the INA4230 IC, which performs simultaneous 16-bit ADC conversion across four independent channels with programmable gain, averaging, and calibration. Each channel measures shunt voltage (±75 µV offset), bus voltage (–0.3V to 48V common-mode), and computes derived values including current (in amperes), power (in watts), and energy (in joules) using internal multipliers.
Hardware design includes 2512-footprint pads (R1/R9/R12/R13) for user-specified shunt resistors, configurable I²C address switches (SW0/SW1), dual alert signaling paths (local LED + buffered bus), and modular interconnection headers (J2/J3) enabling daisy-chained operation with up to four identical EVMs controlled by a single SCB and GUI instance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supported Device | INA4230 only - validated hardware layout, firmware, and GUI integration specific to INA4230's register map and electrical behavior. |
| Current Range | Up to 10A per channel - defined by PCB trace rating and terminal block (J1/J5) limits; requires external shunt or soldered 2512 resistor. |
| Interface Protocol | I²C/SMBus - compatible with 1.2V–5V digital bus voltages; uses R5/R6 pull-up resistors and supports up to 16 addresses via SW0/SW1. |
| Power Source | Micro-USB via TI Sensor Control Board (SCB) - no onboard regulator; derives 3.3V logic and analog supply from SCB. |
| GUI Integration | Web-based INA423XEVM-GUI (dev.ti.com) - enables real-time register read/write, shunt calibration, multi-channel data plotting, and CSV export. |
| Alert Functionality | Dual-path alert signaling - local LED (D2) + open-drain buffered output (U2) routed to J2/J3 for system-level fault propagation. |

FAQ
What is the primary function of the INA4230EVM?
The INA4230EVM is a dedicated evaluation platform for the INA4230 quad-channel current monitor IC. It enables engineers to verify real-world performance of shunt-based current, bus voltage, power, and energy measurements - including register configuration, alert response, multi-channel synchronization, and GUI-driven calibration - before integrating the INA4230 into final designs.
Does the INA4230EVM include the INA4230 IC pre-installed?
Yes, the INA4230EVM ships with the INA4230 IC (U1) pre-soldered and fully functional. The board is not a blank carrier - it contains all necessary bypass capacitors (C1/C2/C7), enable control circuitry (SH-J1 jumper), test points (TP1–TP19), and terminal blocks (J1/J5) configured specifically for the INA4230's pinout and operational requirements.
Can the INA4230EVM operate without the TI Sensor Control Board (SCB)?
No - the INA4230EVM requires the TI Sensor Control Board (SCB) for power delivery, USB communication, and I²C signal routing. The EVM has no standalone USB interface or onboard microcontroller; its J2 and J3 headers are designed exclusively for connection to the SCB or compatible controllers like the PAMB DC081A via verified pin-mapped wiring.
What software tools are required to use the INA4230EVM?
Users must install the TI PAMB/SCB USB driver (sbac253.zip) and access the web-based INA423XEVM-GUI at dev.ti.com/gallery/info/CurrentSensing/INA423XEVM_GUI. No local installation is needed - the GUI runs in Chrome®, Firefox®, or Safari® and communicates directly with the SCB/EVM stack via USB bulk transfer after driver setup.
Is the INA4230EVM compatible with the INA4235 IC?
No - while the INA4230EVM and INA4235EVM share identical mechanical layout and GUI infrastructure, the INA4230EVM is electrically and firmware-validated only for the INA4230. The INA4235 features ±10 µV offset and 0.1% gain error versus the INA4230's ±75 µV and 0.75%, requiring distinct calibration and register handling not supported on the INA4230EVM hardware.
