IR5001S

Overview

The IR5001S is an N+1 ORing controller manufactured by Infineon Technologies, designed for power distribution systems. It supports N:1 input-to-output ratios and utilizes external N-channel FETs rather than internal switches. The device operates within a supply voltage range of 36V to 75V and draws 500 µA of supply current. Key timing parameters include a turn-on delay of 27 µs and a turn-off delay of 130 ns. It is housed in an 8-SOIC package with a width of 3.90mm and functions reliably across a temperature range of 0°C to 85°C.

Feature Summary

• Supports N+1 redundancy configurations for multiple power inputs
• Controls external N-channel MOSFETs for ideal diode emulation
• Provides fast turn-off response to prevent reverse current flow

Applications

• -48V distributed power systems
• Redundant power supply architectures
• Telecommunications power infrastructure

Procurement Notes

Verify component status as the IR5001S is listed as obsolete or end-of-life. Confirm availability through authorized distributors or secondary market sources. Check RoHS compliance status, which may differ from current standards. Ensure the 8-SOIC package dimensions match PCB footprint requirements. Validate supply voltage compatibility with existing system rails before integration.

Selection Notes

Select this controller when designing redundant power architectures requiring N+1 configuration. Ensure external N-channel MOSFETs are compatible with the control logic. Verify that the 36V to 75V supply range aligns with the system's operating voltage. Consider the 8-SOIC package size for board space constraints. Evaluate thermal performance within the specified 0°C to 85°C operating range.

Part Context

The IR5001S belongs to the IR5001 family of OR controllers. It serves as a specialized power management IC for managing parallel power sources. The component integrates control logic for ideal diode applications without internal switching elements. It complements other Infineon power solutions in industrial and telecom sectors.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the component is marked as obsolete, alternative solutions must be evaluated based on functional equivalence. Verify pinout compatibility and electrical specifications when selecting replacement devices.
