INA203AIDGSTG4

Current Regulation/Management Overview

The INA203AIDGSTG4 is a high-side current shunt monitor manufactured by Texas Instruments, designed for unidirectional measurement applications. It operates within a supply voltage range of 2.7 V to 18 V and supports input voltages from -16 V to 80 V. The device draws a typical operating supply current of 2.8 mA. It is housed in a 10-pin MSOP package and is rated for operation between -40°C and +125°C.

Current Regulation/Management Feature Summary

• Provides accurate unidirectional current monitoring via external shunt resistor measurement
• Supports high common-mode input voltage ranges up to 80 V
• Operates with low supply current suitable for power-constrained systems

Current Regulation/Management Applications

• High-side current sensing in industrial control systems
• Power management unit monitoring in battery-powered devices
• Overcurrent protection circuits in automotive electronics

Current Regulation/Management Procurement Notes

Verify the specific suffix 'DGST' confirms the MSOP-10 package and tape-and-reel orientation. Confirm RoHS compliance status through official manufacturer documentation. Check for obsolescence notices as component lifecycle status may vary by region. Ensure compatibility with existing PCB footprint designs before procurement.

Current Regulation/Management Selection Notes

Select this component when high-side measurement is required with inputs exceeding standard supply rails. The wide common-mode range accommodates various bus architectures. Consider the MSOP-10 package constraints for thermal dissipation and board space. Validate that the unidirectional capability meets the system's monitoring requirements without needing bidirectional support.

Current Regulation/Management Part Context

This part belongs to the INA203 series of current monitors. It shares functional similarities with other high-side amplifiers but is optimized for specific voltage ranges and accuracy levels. The 'A' grade indicates tighter performance specifications compared to standard grades. It serves as a dedicated solution for precise current feedback in power regulation loops.

Current Regulation/Management Replacement Considerations

Direct substitutes include the INA203AIDGSR for reel packaging variations or the INA203AIPW for TSSOP-14 package alternatives. Verify pinout compatibility and electrical parameter alignment before substitution. Cross-reference datasheets to ensure equivalent common-mode voltage handling and supply current characteristics.
