INA284AID

Current Regulation/Management Overview

The INA284AID is a high-side current sense amplifier from Texas Instruments, designed for precise measurement of current flowing through shunt resistors in power distribution systems. It features a wide common-mode voltage range extending up to 80V, allowing operation in high-voltage environments without requiring level shifting. The device offers a fixed gain of 25 V/V, which simplifies system design by providing a direct output proportional to the sensed current. With low input offset voltage and high common-mode rejection ratio, it ensures accurate readings even under noisy conditions. The SOIC-8 package facilitates compact PCB integration.

Current Regulation/Management Feature Summary

• High-side current sensing capability with wide common-mode voltage range
• Fixed gain configuration for simplified signal conditioning
• Low input offset voltage for enhanced measurement accuracy
• Robust common-mode rejection for noise immunity

Current Regulation/Management Applications

• Power distribution units in industrial equipment
• Overcurrent protection circuits in motor drives
• Current monitoring in battery management systems
• Load switching applications in automotive electronics

Current Regulation/Management Procurement Notes

Verify the specific suffix 'AID' corresponds to the intended temperature grade and package type during procurement. Confirm that the supplier provides genuine Texas Instruments components to ensure performance reliability. Check for any recent obsolescence notices or lifecycle status updates before placing orders. Ensure storage conditions comply with manufacturer guidelines to prevent moisture sensitivity issues.

Current Regulation/Management Selection Notes

Select this component when a fixed gain of 25 V/V meets the system's dynamic range requirements. Consider the 80V common-mode limit against the maximum bus voltage in the application. Evaluate the need for high-side sensing versus low-side alternatives based on ground reference constraints. Verify that the SOIC-8 footprint aligns with existing board layout specifications.

Current Regulation/Management Part Context

The INA284 belongs to Texas Instruments' family of precision current sense amplifiers. It complements other models like the INA280 and INA281, offering different gain options and bandwidth characteristics. This series is engineered for robust performance in demanding industrial and automotive environments, providing reliable current monitoring solutions.

Current Regulation/Management Replacement Considerations

Direct pin-to-pin replacements may include the INA280AID or INA281AID if gain adjustments are acceptable. Verify compatibility regarding common-mode voltage limits and output swing capabilities before substitution.
