ADM1041ARQ-REEL7

Overview

The ADM1041ARQ-REEL7 is a secondary-side management integrated circuit designed for server power supplies. It provides voltage control, current sharing, and housekeeping functions for single-output N+1 configurations. The device operates within a supply voltage range of 4.5V to 5.5V and draws a typical supply current of 6mA. It supports surface mount mounting and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates voltage control and current share capabilities to minimize external component counts
• Eliminates the need for additional discrete components in secondary-side management applications
• Provides dedicated housekeeping functions for server power supply architectures

Applications

• Secondary-side controller for N+1 server power supplies
• Single output power supply voltage control systems
• Current share management in redundant power architectures

Procurement Notes

Verify the specific suffix REEL7 against official Analog Devices documentation to confirm reel packaging specifications. Ensure compatibility with existing secondary-side management designs by cross-referencing the pinout and electrical characteristics with the latest datasheet. Confirm that the operating temperature range meets the thermal requirements of the target server environment.

Selection Notes

Select this component when designing secondary-side controllers for server power supplies requiring integrated current sharing and voltage regulation. It is suitable for applications needing to reduce bill-of-materials complexity by eliminating external housekeeping components. Verify that the 4.5V to 5.5V supply range aligns with the system's auxiliary power rails.

Part Context

This part belongs to the ADM1041 family of power management ICs from Analog Devices. These devices are engineered specifically for high-reliability server power infrastructure. The family focuses on simplifying secondary-side management by combining multiple control functions into a single package, thereby enhancing system density and reducing design complexity.

Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Ensure any replacement maintains compatibility with N+1 server power supply architectures and secondary-side management protocols.
