Overview

The INA230AIRGTR is a high-side or low-side current-shunt and power monitor featuring an I2C/SMBus-compatible interface. This digital monitor measures shunt voltage drops, bus supply voltage, and provides calculated power and current readings with a high-resolution 16-bit ADC.

Why Choose This Part

The device offers exceptional precision with a 0.5% accuracy rating and a low 330uA quiescent current, making it suitable for power-sensitive designs. Its 16-bit ADC provides high resolution for both small and large current flows, while the programmable alert threshold enables rapid response to over-current or over-voltage conditions.

Applications

Battery Management Systems
Accurately monitor charge and discharge cycles in portable equipment and battery packs with precise power calculation.
Telecom Infrastructure
Real-time power monitoring for high-reliability networking hardware with bus voltages up to 36V.
Industrial Automation
Precision current sensing for motor control feedback loops and system health monitoring in factory environments.
Computing Servers
Slot-level power consumption tracking to optimize thermal management and power distribution efficiency.

Getting Started

Engineers can evaluate this part using the INA230EVM evaluation module, which interfaces with TI's SM-USB-DIG software. When designing the PCB, ensure the shunt resistor is placed as close as possible to the IN+ and IN- pins to minimize trace resistance errors and use Kelvin sensing connections for maximum accuracy.
