Overview
The ADM1073ARUZ-REEL is a single-channel hot swap controller manufactured by Analog Devices Inc., designed for -48V applications. It features an external N-channel MOSFET switch and integrates programmable 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 is housed in a 14-TSSOP package and supports an operating temperature range from -40°C to +85°C. Key functional attributes include automatic retry capabilities upon fault clearance.
Feature Summary
- Integrates programmable current limiting and fault timeout protection for controlled power-up sequences
- Includes overvoltage protection and undervoltage lockout mechanisms to safeguard connected loads
- Supports automatic retry functionality to restore power after transient fault conditions are resolved
Applications
- -48V telecommunications infrastructure systems
- Industrial control equipment requiring safe insertion and removal
- Telecom backplane power distribution modules
Procurement Notes
Verify the specific suffix 'REEL' indicates tape-and-reel packaging when sourcing. Confirm the component status as obsolete or limited availability through official Analog Devices channels. Ensure compatibility with existing board layouts utilizing the 14-TSSOP footprint. Cross-reference the direct replacement part number ADM1073ARUZ for updated manufacturing data.
Selection Notes
Select this controller for designs requiring robust protection in negative voltage environments. Evaluate the need for external MOSFET selection based on current requirements. Consider the 14-TSSOP package constraints for thermal management. Verify that the -48V input range aligns with the system's power architecture before integration.
Part Context
This component belongs to the ADM1073 family of hot swap controllers from Analog Devices. It serves as a specialized power management IC for protecting circuits during live insertion. The ARUZ variant denotes a lead-free, RoHS-compliant version in a TSSOP package. It addresses reliability concerns in high-value electronic systems by preventing surge currents.
Replacement Considerations
The direct substitute is the ADM1073ARUZ. Verify pin-to-pin compatibility and identical electrical specifications. Check for any updates in the datasheet regarding recommended external components or layout guidelines.
