INA207AIPWR

Current Regulation/Management Overview

The INA207AIPWR is a high-side current sense amplifier manufactured by Texas Instruments, featuring a fixed gain of 50 V/V. It operates with an input voltage range from -16 V to 80 V and includes dual window comparators for fault detection. The device supports a supply voltage of 3 V to 5.5 V, draws 1.5 mA of quiescent current, and maintains accuracy within ±3.5%. It functions reliably across a temperature range of -40°C to +125°C and is housed in a 14-pin TSSOP package.

Current Regulation/Management Feature Summary

• Integrated dual window comparators for real-time over-current and under-current fault monitoring
• High common-mode voltage tolerance supporting inputs from -16 V to 80 V
• Fixed 50 V/V gain option optimized for precise current sensing applications

Current Regulation/Management Applications

• Industrial motor control systems requiring high-side current monitoring
• Power distribution units with fault protection capabilities
• Automotive electronics operating under wide voltage fluctuations

Current Regulation/Management Procurement Notes

Verify the specific suffix 'A' indicates the 50 V/V gain variant distinct from other family members. Confirm the 'PW' package code corresponds to the 14-pin TSSOP form factor. Ensure compatibility with the required operating temperature range of -40°C to +125°C for your specific environment. Cross-reference the datasheet revision to confirm pinout consistency.

Current Regulation/Management Selection Notes

Select this component when a fixed 50 V/V gain is required for high-side sensing between -16 V and 80 V. It is suitable for designs needing integrated comparator functionality without external components. Consider the TSSOP-14 package constraints for PCB layout. Evaluate if the ±3.5% accuracy meets system requirements compared to higher precision alternatives.

Current Regulation/Management Part Context

Part of the INA20x series of current sense amplifiers, which offers multiple gain options (20, 50, and 100 V/V) within a unified package and feature set. This series integrates comparators to simplify design complexity. The INA207 specifically targets applications needing moderate gain with robust fault detection capabilities.

Current Regulation/Management Replacement Considerations

INA206AIPWR (20 V/V gain), INA208AIPWR (100 V/V gain). These share identical pinouts and features but differ in amplifier gain.
