Overview

The INA228AIDGSR is an ultra-precise, 20-bit digital power monitor with an I2C-compatible interface designed for high-side or low-side sensing. It supports a wide common-mode voltage range up to 85V and provides accurate measurements of current, bus voltage, power, energy, and charge accumulation.

Why Choose This Part

The 20-bit ADC provides exceptional resolution for measuring very small shunt voltages, reducing the power loss associated with high-resistance shunts. Integrated energy and charge accumulation buffers offload complex math from the host MCU, and the 85V common-mode range eliminates the need for external isolation or voltage dividers in many high-voltage systems.

Applications

High-Voltage Battery Management
Monitoring state-of-charge and state-of-health in high-cell-count battery packs up to 85V.
Industrial Power Monitoring
Precise energy logging and power consumption analysis for industrial automation equipment.
Data Center Infrastructure
Real-time power monitoring in server racks and telecommunications power distribution units.
Renewable Energy Systems
Measuring power output and energy accumulation in solar string inverters and energy storage systems.

Getting Started

Evaluation can be performed using the INA228EVM, which connects to a PC via the TI SCB controller for use with the GUI Composer software. In custom firmware, configure the I2C address via the ADDR pin and set the calibration register to begin receiving scaled current and power readings.
