ADM1073ARU

Overview

The ADM1073ARU is a single-channel hot swap controller designed for -48V telecommunications applications. Manufactured by Analog Devices Inc., it integrates programmable features including current limiting, fault timeout, overvoltage protection (OVP), and undervoltage lockout (UVLO). The device operates with a supply voltage range of -80V to -35V and draws a typical supply current of 300 µA. It supports automatic retry functionality upon fault clearance. The component is housed in a 14-TSSOP surface-mount package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

Integrates programmable current limiting and fault timeout protection mechanisms
Provides overvoltage protection and undervoltage lockout capabilities
Supports automatic retry operations following fault conditions

Applications

-48V telecommunications power systems
Hot swap controller implementations
Telecom infrastructure power management

Procurement Notes

Verify the obsolete status of this specific part number before procurement planning. Confirm availability of the direct replacement ADM1073ARUZ from Analog Devices Inc. Ensure design files are updated to reflect any potential package or pinout differences between the legacy and replacement components. Check for RoHS compliance updates associated with the suffix change.

Selection Notes

Select this component for -48V telecom environments requiring precise hot swap control. Evaluate the need for programmable protection thresholds against system requirements. Consider the 14-TSSOP footprint constraints during PCB layout. Verify that the 300 µA supply current aligns with standby power budgets. Assess thermal performance within the specified -40°C to +85°C operational range.

Part Context
