IR5001STR

Overview

The IR5001STR is a universal high-speed controller and N-channel power MOSFET driver designed for active ORing and reverse polarity protection applications. It operates with an input voltage range of 36V to 75V, supporting up to 100V continuous application via integrated clamps. The device features a typical turn-off delay of 130ns and a turn-on delay of 27µs, with a supply current of 500µA. Packaged in an 8-SOIC surface-mount format, it provides a peak turn-off gate drive current of 3A. The component is rated for operation between 0°C and 85°C and supports N:1 input-to-output ratios.

Feature Summary

• Universal active ORing controller with integrated N-channel MOSFET driver
• High-speed switching with 130ns typical turn-off delay to minimize voltage sags
• Integrated voltage clamps on comparator inputs allow continuous application of up to 100V
• Asymmetrical offset voltage prevents potential oscillations at light load conditions

Applications

• -48V/-24V input active ORing for carrier class communication equipment
• Reverse input polarity protection
• Redundant DC-DC and AC-DC power supplies output ORing

Procurement Notes

Verify the specific suffix 'STR' against official Infineon documentation to confirm reel packaging versus tube variants. Confirm RoHS compliance status as older IR5001 data indicates non-compliance. Check part lifecycle status as some sources list the base model as obsolete. Ensure the supplier provides valid traceability for the SOIC-8 package.

Selection Notes

Select this component for redundant power architectures requiring fast fault isolation. The 3A peak gate drive current supports efficient switching of external N-channel MOSFETs. Verify that the 36V to 75V operating range aligns with the system bus voltage. Consider the 8-SOIC package constraints for thermal management and PCB layout space.

Part Context

The IR5001 series serves as a dedicated solution for implementing active ORing logic using discrete N-channel power MOSFETs. It replaces complex discrete comparator and driver circuits with a single integrated controller. The STR variant typically denotes tape-and-reel packaging suitable for automated surface-mount assembly processes.
