INA286AIDR

Current Regulation/Management Overview

The INA286AIDR is a high-accuracy, bidirectional current shunt monitor manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 18 V and draws a typical quiescent current of 600 µA. The device supports both high-side and low-side sensing with a wide common-mode voltage range from -14 V to 80 V. It features an accuracy of 1.4% and a gain-bandwidth product of 10 kHz. The component is housed in an SOIC-8 surface-mount package and functions reliably across an operating temperature range of -40°C to +125°C.

Current Regulation/Management Feature Summary

• Bidirectional output capability for monitoring current flow in both directions
• Wide common-mode voltage range supporting -14 V to 80 V inputs
• High accuracy specification ensuring precise measurement performance
• Low power consumption suitable for energy-efficient system designs

Current Regulation/Management Applications

• Industrial process control systems requiring precise current monitoring
• Power distribution units for load management and protection
• Battery management systems in portable and stationary applications
• Overcurrent protection circuits in consumer electronics

Current Regulation/Management Procurement Notes

Verify the specific suffix 'DR' indicates the tape-and-reel packaging configuration when ordering. Confirm that the A-grade accuracy variant meets the precision requirements of the target application. Ensure the SOIC-8 footprint matches the PCB layout design rules. Check for moisture sensitivity level compliance if the component has been exposed to ambient conditions prior to assembly.

Current Regulation/Management Selection Notes

Select this component when bidirectional current sensing is required alongside a wide common-mode input range. The 1.4% accuracy makes it suitable for applications demanding higher precision than standard monitors. Consider the 600 µA quiescent current for battery-operated devices where power efficiency is critical. The SOIC-8 package offers a compact solution for space-constrained designs compared to larger industrial packages.

Current Regulation/Management Part Context

The INA286 belongs to the INA28x family of current shunt monitors designed for high-performance applications. It complements other variants like the INA285 and INA283, which may differ in quiescent current or specific accuracy grades. This series addresses the need for reliable current monitoring in harsh environments with high common-mode voltages.

Current Regulation/Management Replacement Considerations

The INA285AIDR serves as a functional substitute within the same family, though it typically exhibits a higher quiescent current of 900 µA. Verify that the increased power consumption aligns with the thermal and efficiency constraints of the existing design before swapping components.
