IR2172SPBF

Current Regulation/Management Overview

The IR2172SPBF is a linear current sensing integrated circuit manufactured by Infineon Technologies. It operates within an input voltage range of 9.5V to 20V and provides a fixed output current of 20mA. The device is housed in an 8-SOIC surface-mount package with a maximum power dissipation of 625mW. It supports a wide operating temperature range from -40°C to +125°C and features a high common-mode rejection capability suitable for sensing voltages up to 600V.

Current Regulation/Management Feature Summary

• Linear current sensing architecture for precise monitoring
• High common-mode voltage tolerance up to 600V
• Fixed 20mA output current drive capability
• Wide operating temperature range for industrial environments

Current Regulation/Management Applications

• Motor drive current monitoring
• Power supply overcurrent protection
• Industrial control system sensing

Current Regulation/Management Procurement Notes

Verify the specific suffix SPBF confirms RoHS compliance status against official Infineon documentation, as legacy variants may differ. Confirm the SOIC-8 package footprint matches PCB design requirements. Check for obsolescence notices or end-of-life declarations from the manufacturer before finalizing procurement plans.

Current Regulation/Management Selection Notes

Select this component when a linear current sense solution with high common-mode voltage tolerance is required. Ensure the application voltage does not exceed the 600V limit. Verify that the 20mA output current meets the downstream interface requirements without additional buffering.

Current Regulation/Management Part Context

This part belongs to the IR2172 family of current sense amplifiers. It serves as a specialized PMIC component for power management applications requiring isolated or high-side current measurement capabilities in harsh electrical environments.

Current Regulation/Management Replacement Considerations

Consult official Infineon substitution guides for verified alternatives. Generic equivalents may lack the specific 600V common-mode rating or 20mA output specification.
