INA232AIDDFR

Current Regulation/Management Overview

The INA232AIDDFR is a high-precision digital power monitor manufactured by Texas Instruments. It features a 16-bit analog-to-digital converter (ADC) and an I²C/SMBus-compatible interface for reporting current, voltage, and power measurements. The device supports both high-side and low-side current sensing configurations. It operates from a single power supply ranging from 1.7 V to 5.5 V and is housed in an 8-pin SOT-23-THN (DDF) package. The component is rated for an operating temperature range of -40°C to +125°C.

Current Regulation/Management Feature Summary

• Provides precise monitoring of current, voltage, and power via a 16-bit ADC
• Supports bidirectional current sensing on either the high side or low side
• Communicates using standard I²C and SMBus protocols

Current Regulation/Management Applications

• Digital bus voltage monitoring
• High-side or low-side current sensing in power systems
• Power management in portable and industrial equipment

Current Regulation/Management Procurement Notes

Verify the specific suffix DDFR indicates tape-and-reel packaging when ordering. Confirm the A-grade accuracy specifications match your system requirements. Ensure the SOT-23-THN footprint aligns with your PCB layout constraints. Check that the I²C address configuration meets your bus topology needs before finalizing procurement.

Current Regulation/Management Selection Notes

Select this component when precise digital measurement of current, voltage, and power is required in space-constrained designs. The 16-bit resolution offers higher accuracy compared to lower-bit monitors. The wide supply voltage range allows flexibility in system design. Consider the thermal performance within the specified temperature range for reliable operation in harsh environments.

Current Regulation/Management Part Context

This part belongs to the INA232 family of digital power monitors from Texas Instruments. It shares core functionality with other variants but differs in packaging and grade. The DDFR suffix specifically denotes the reel packaging format. It is designed for applications requiring accurate energy monitoring without external shunt amplifiers.

Current Regulation/Management Replacement Considerations

Direct substitutes include other INA232 variants with different packages or grades, such as INA232AIDDT. Verify pin compatibility and electrical specifications before substitution. Ensure the replacement maintains the required I²C interface and accuracy levels for your application.
