Overview

The INA232BIDDFR is a 16-bit digital current, voltage, and power monitor with an I2C and SMBus-compatible interface. It supports both high-side and low-side sensing across a wide bus voltage range from -0.3V to 48V, making it suitable for a variety of power management applications.

Why Choose This Part

The device features a high-resolution 16-bit ADC with a low 50-microvolt maximum offset, ensuring high precision even at small sense voltages. It is exceptionally power-efficient with a typical operating current of 0.3mA and a shutdown current of 2.2uA, ideal for battery-powered systems.

Applications

Battery Management Systems
Accurately monitor charge and discharge cycles in lithium-ion battery packs using high-side sensing.
Industrial Power Monitoring
Track power consumption in industrial automation equipment with programmable alert limits for over-current conditions.
Telecom Infrastructure
Monitor 48V power rails for precision current draw and voltage stability in networking hardware.
Server Power Supplies
Provide real-time power telemetry to system controllers via the 1.2V-compliant I2C interface.
