Product Overview: INA230AIDGSR from Texas Instruments

The INA230AIDGSR is a state-of-the-art current shunt and power monitor with an I2C-compatible interface. This precision device from Texas Instruments is designed for seamless integration into industry applications requiring accurate power monitoring. With its wide common-mode input voltage range of 0 to 28V, it is highly versatile and well-suited for systems that operate at multiple voltage levels.

At the heart of the INA230AIDGSR is a 16-bit delta-sigma ADC that provides the capability to measure voltage, current, and power. The high-precision monitoring is complemented by the device's programmable calibration value, which allows users to scale the current measurement for various shunt resistor values and configurations. This enables the INA230AIDGSR to cater to a broad spectrum of power management requirements.

With its ability to measure both the shunt voltage drop and bus supply voltage, the INA230AIDGSR provides a comprehensive solution for power consumption analysis. The device's digital interface supports up to 16 programmable addresses on the I2C bus, allowing multiple devices to be used on the same bus for complex power monitoring systems.

The INA230AIDGSR also boasts an impressive feature set that includes an integrated multiplier that enables energy and power calculations, as well as programmable alert functions for quick response to overcurrent or other predefined events. This functionality enhances system protection and reliability, making it ideal for applications such as servers, power supplies, battery management, and portable instrumentation.

Key features of the INA230AIDGSR include:

• High accuracy with a maximum offset of 100 µV
• Configurable averaging options
• Programmable alert functions for overcurrent, undercurrent, overvoltage, and undervoltage
• Operating temperature range from -40°C to 125°C
• Small VSSOP (Very Small Shrink Outline Package) for space-saving on PCBs

The INA230AIDGSR is an ideal choice for designers looking for a compact, precise, and reliable power monitoring solution. Its advanced features and ease of use make it a valuable component in any power-sensitive application.
