INA302A3QPWRQ1

Current Regulation/Management Overview

The INA302A3QPWRQ1 is a high-side and low-side current sense amplifier manufactured by Texas Instruments, designed for automotive applications. It operates within an input voltage range of 0V to 36V and supports a wide operating temperature range from -40°C to 125°C. The device is housed in a 14-TSSOP package with a width of 4.40mm. It holds AEC-Q100 qualification and complies with RoHS3 standards. The component is classified as a current sensing regulator suitable for surface mount installation.

Current Regulation/Management Feature Summary

• Supports both high-side and low-side current sensing configurations
• Qualified for automotive electronics under AEC-Q100 standards
• Operates across extended industrial temperature ranges

Current Regulation/Management Applications

• Automotive battery monitoring systems
• High-side current protection circuits
• Low-side load switching detection

Current Regulation/Management Procurement Notes

Verify the specific suffix QPWRQ1 confirms automotive grade classification and TSSOP packaging. Ensure compatibility with 0V to 36V common mode input requirements. Confirm RoHS3 compliance status matches project environmental regulations. Validate that the 14-pin form factor fits the designated PCB footprint constraints.

Current Regulation/Management Selection Notes

Select this component when bidirectional or unidirectional current monitoring is required in automotive environments. Consider the 14-TSSOP package size for space-constrained designs. Evaluate the 36V input limit against system voltage peaks. Verify thermal performance within the specified -40°C to 125°C operational window for reliability.

Current Regulation/Management Part Context

This part belongs to the INA302-Q1 family of current sense amplifiers. It shares functional similarities with other automotive-grade sensors but is distinct in its specific gain configuration and package type. The series targets robust current measurement in harsh automotive electrical environments.

Current Regulation/Management Replacement Considerations

Check datasheet cross-reference sections for direct pin-compatible alternatives. Verify if lower-grade commercial versions meet the AEC-Q100 requirement. Ensure substitute parts support the same 0V to 36V input range.
