INA286AIDGKR

Current Regulation/Management Overview

The INA286AIDGKR is a bidirectional current sense amplifier manufactured by Texas Instruments, housed in an 8-pin VSSOP package. It supports a supply voltage range of 2.7 V to 18 V with a maximum operating supply current of 600 uA. The device offers high accuracy with a maximum error of 1.4% and operates within a temperature range of -40°C to +125°C. Designed for high or low-side sensing, it handles common-mode voltages from -14 V to 80 V.

Current Regulation/Management Feature Summary

• Supports bidirectional current sensing for both sourcing and sinking applications
• Enables high-side or low-side measurement configurations
• Operates with wide common-mode voltage range extending to negative potentials

Current Regulation/Management Applications

• Battery management systems requiring bidirectional current monitoring
• Industrial process control loops with shunt-based current feedback
• Overcurrent protection circuits in power distribution units

Current Regulation/Management Procurement Notes

Verify the specific suffix 'DGKR' corresponds to the VSSOP-8 tape and reel packaging configuration. Confirm that the A-grade accuracy specification meets the system tolerance requirements. Ensure the thermal performance aligns with the intended ambient operating conditions within the specified -40°C to +125°C range. Check for moisture sensitivity level compliance during storage and reflow processes.

Current Regulation/Management Selection Notes

Select this component when bidirectional current monitoring is required alongside high common-mode voltage rejection. The low supply current makes it suitable for energy-constrained environments. Compare against the INA282 if only unidirectional sensing is needed, as the INA286 provides additional functionality for reverse current detection without increasing complexity.

Current Regulation/Management Part Context

This part belongs to the INA286 family of precision current sense amplifiers. It shares architectural similarities with other devices in the series but is distinguished by its bidirectional capability and specific packaging variant. The device integrates precision resistors and amplification stages on a single silicon die to minimize external component count.

Current Regulation/Management Replacement Considerations

INA286AIDR serves as a pin-compatible alternative in SOIC-8 packaging. For unidirectional applications, the INA282 series may offer cost-effective substitution. Verify that any substitute maintains the same 1.4% accuracy and common-mode voltage specifications.
