IR2172PBF

Current Regulation/Management Overview

The IR2172PBF is a current sense regulator manufactured by Infineon Technologies, housed in an 8-PDIP package. It operates with an input voltage range of 9.5 V to 20 V and provides a fixed output current of 20 mA. Designed for through-hole mounting, the device functions within a temperature range of -40°C to +125°C. This component is classified under PMIC current regulation management.

Current Regulation/Management Feature Summary

• Provides regulated current sensing functionality
• Supports wide operating temperature ranges

Current Regulation/Management Applications

• Power management systems requiring current regulation
• Industrial control circuits
• General-purpose current monitoring applications

Current Regulation/Management Procurement Notes

Verify the obsolete status before procurement as this part may be discontinued. Confirm RoHS compliance requirements against specific project standards. Ensure the 8-DIP package fits the target PCB layout. Check for valid replacement components if new designs are required.

Current Regulation/Management Selection Notes

Select this component for applications needing a simple, fixed-output current source. The 20 mA output is suitable for standard signaling or biasing needs. Verify that the 9.5 V to 20 V input range matches the system supply. Consider the PDIP package constraints for automated assembly.

Current Regulation/Management Part Context

This part belongs to Infineon's legacy power management portfolio. It serves as a dedicated current sense regulator rather than a general-purpose driver. The 8-pin DIP format indicates its use in traditional through-hole manufacturing environments.
