INA203AQPWRQ1

Current Regulation/Management Overview

The INA203AQPWRQ1 is an automotive-grade, high-side current sense amplifier manufactured by Texas Instruments. It features a wide common-mode voltage range from -16 V to 80 V and operates on a single supply voltage between 2.7 V and 5.5 V. The device provides a fixed gain of 100 V/V with an open-drain output configuration. It is qualified under AEC-Q100 standards for automotive applications, ensuring reliability in harsh environments.

Current Regulation/Management Feature Summary

• Supports bidirectional current sensing with a wide common-mode voltage range extending into negative voltages.
• Features an open-drain output interface suitable for interfacing with various logic levels.
• Qualified for automotive applications meeting AEC-Q100 reliability standards.

Current Regulation/Management Applications

• Automotive battery monitoring systems
• High-side current protection circuits
• Industrial motor control feedback

Current Regulation/Management Procurement Notes

Verify the specific suffix 'PWRQ1' confirms the TSSOP-14 package and automotive grade qualification. Ensure compatibility with system voltage requirements, as the device supports a wide input range but requires a valid supply connection. Confirm moisture sensitivity handling procedures are followed during assembly to maintain component integrity.

Current Regulation/Management Selection Notes

Select this component when a high-side current monitor with bidirectional capability is required in automotive or industrial settings. It is suitable for applications needing a fixed gain of 100 V/V and open-drain output. Consider the -16 V to 80 V common-mode range for systems with significant voltage fluctuations or negative transients.

Current Regulation/Management Part Context

This part belongs to the INA203 family of current sense amplifiers designed for robust performance in demanding environments. The 'Q1' suffix indicates automotive qualification, while 'PWR' denotes the plastic small-world package type. It serves as a specialized solution for precise current measurement in complex electronic systems.

Current Regulation/Management Replacement Considerations

Check datasheets for alternative high-side current sense amplifiers with similar gain and common-mode ranges. Verify pinout compatibility if substituting within the same package type. Ensure any replacement meets the same AEC-Q100 automotive reliability standards.
