IR2170

Current Regulation/Management Overview

The IR2170 is a current sense regulator manufactured by Infineon Technologies, designed for power management applications. It operates with an input voltage range of 9.5V to 20V and supports a maximum sensing voltage of 600V. The device provides a regulated output current of 1mA, facilitating precise current monitoring in electronic circuits. It is housed in an 8-DIP package with a standard pin spacing of 7.62mm (0.300 inches). This component serves as a dedicated solution for managing and regulating current sensing tasks within high-voltage systems.

Current Regulation/Management Feature Summary

• Provides regulated 1mA output for accurate current sensing
• Supports high-voltage sensing up to 600V
• Operates within a 9.5V to 20V input supply range

Current Regulation/Management Applications

• Power management circuitry
• Current monitoring systems
• High-voltage electronic circuit protection

Current Regulation/Management Procurement Notes

Verify the specific datasheet version when sourcing, as Infineon acquired International Rectifier. Confirm that the 8-DIP package matches your PCB footprint requirements. Ensure the application voltage does not exceed the 600V limit. Check for RoHS compliance status if required by your manufacturing standards. Cross-reference the part number with official Infineon documentation to avoid counterfeit components.

Current Regulation/Management Selection Notes

Select this component when a fixed 1mA output current is required for current sensing rather than variable regulation. Consider the 600V sensing capability for high-side or isolated applications. Evaluate the 8-DIP package size against available board space. Compare input voltage requirements against the 9.5V-20V operational range to ensure compatibility with your system's power supply.

Current Regulation/Management Part Context

The IR2170 belongs to the current regulation and management category of power management ICs. Originally developed by International Rectifier, it is now part of Infineon Technologies' portfolio following their acquisition. It functions specifically as a current sense regulator, distinct from general-purpose amplifiers or linear regulators, targeting niche applications requiring precise current feedback.

Current Regulation/Management Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Verify compatibility with existing circuit designs before considering alternative current sense regulators from other manufacturers.
