INA170EA/2K5

Current Regulation/Management Overview

The INA170EA/2K5 is a high-side current monitor integrated circuit manufactured by Texas Instruments. It operates within an input voltage range of 2.7V to 60V and functions across a temperature range of -40°C to 85°C. The device provides a differential output proportional to the voltage drop across an external shunt resistor, with a specified accuracy of ±0.5%. Packaged in an 8-VSSOP surface-mount case, it is designed for precise current sensing applications requiring high common-mode voltage tolerance.

Current Regulation/Management Feature Summary

• Provides accurate current monitoring through a differential output signal proportional to shunt voltage
• Supports high common-mode input voltages up to 60V for flexible placement in power circuits
• Delivers manufacturing-grade precision with a guaranteed accuracy of ±0.5%

Current Regulation/Management Applications

• High-side current sensing in power distribution units
• Battery management systems requiring precise charge/discharge monitoring
• Industrial motor control circuits for overcurrent protection

Current Regulation/Management Procurement Notes

Verify the specific suffix EA/2K5 against official Texas Instruments documentation to confirm package type and reel quantity specifications. Ensure compatibility with the target application's voltage and temperature requirements before procurement. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability.

Current Regulation/Management Selection Notes

Select this component when high-side sensing is required with a wide common-mode voltage range up to 60V. The ±0.5% accuracy specification makes it suitable for applications demanding precise current measurement without complex calibration. Consider the 8-VSSOP package constraints for PCB layout and thermal management during the design phase.

Current Regulation/Management Part Context

The INA170 belongs to Texas Instruments' family of current shunt monitors designed for robust performance in noisy environments. This specific variant integrates precision amplification and level shifting to handle high common-mode signals while providing a ground-referenced output. It serves as a critical interface between power stages and microcontroller-based control logic.
