ADM1073ARU-REEL

Overview

The ADM1073ARU-REEL is a full-feature hot swap controller designed for -48V applications, manufactured by Analog Devices Inc. It operates within a supply voltage range of -80V to -35V and draws a typical supply current of 300 µA. The device is housed in a 14-TSSOP surface-mount package with a width of 4.40mm. It supports an operating temperature range from -40°C to +85°C. Key programmable features include current limiting, fault timeout, overvoltage protection (OVP), and undervoltage lockout (UVLO). The component includes automatic retry functionality upon fault clearance.

Feature Summary

• Integrates programmable current limiting and fault timeout controls for precise power-up sequencing
• Provides comprehensive protection mechanisms including overvoltage protection and undervoltage lockout
• Supports automatic retry operations to restore system function after transient fault conditions

Applications

• -48V telecommunications infrastructure systems
• Hot swap controller implementations in industrial equipment
• Power management units requiring robust fault protection

Procurement Notes

Verify the exact suffix designation when sourcing, as the REEL variant indicates tape-and-reel packaging distinct from tube configurations. Confirm that the specific revision matches design requirements, as older revisions may be obsolete. Ensure compatibility with existing thermal management solutions given the TSSOP package constraints. Cross-reference the manufacturer part number against authorized distributors to avoid counterfeit components.

Selection Notes

Select this component for designs requiring dedicated -48V hot swap control with integrated protection logic. Consider the 14-TSSOP footprint for space-constrained layouts. Evaluate the need for programmable parameters against fixed-function alternatives. Verify that the supply current and thermal characteristics align with the target application's power budget and environmental conditions.

Part Context

This part belongs to the ADM1073 family of hot swap controllers from Analog Devices. It serves as a specialized power management IC for protecting circuits during insertion or removal in live systems. The device complements other -48V interface solutions by providing active control over power delivery sequences and fault handling.

Replacement Considerations

The direct substitute is the ADM1073ARUZ. Verify pin-to-pin compatibility and functional equivalence before substitution. Check if the Z suffix denotes lead-free compliance or minor packaging updates relative to the original specification.
