Overview
The ADM1075-2ARUZ is a full-featured, negative voltage hot swap controller designed for safe insertion and removal of boards from live backplanes. It operates with negative supply voltages typically ranging from -35 V to -80 V. The device integrates constant power foldback for FET SOA protection and provides high-accuracy digital current and voltage measurement. It features a 28-lead TSSOP package and supports an operating junction temperature range from -40°C to +105°C.
Feature Summary
- Provides precise and robust current limiting with protection against transient and non-transient short circuits, overvoltage, and undervoltage conditions.
- Integrates a shunt regulator that ensures excellent voltage transient immunity and flexible operating ranges.
- Includes a PMBus/I2C interface for control, telemetry, and fault recording capabilities.
Applications
- Telecommunication and data communication equipment
- Central office switching
- -48 V distributed power systems
- Negative power supply control
- High availability servers
Procurement Notes
Verify the specific suffix '2' in the part number ADM1075-2ARUZ against official Analog Devices documentation to confirm if it denotes a distinct variant or packaging specification compared to the standard ADM1075. Ensure compatibility with -48 V backplane architectures requiring negative voltage hot swap management.
Selection Notes
Select this component for applications requiring negative voltage hot swap control with integrated telemetry. The internal shunt regulator allows direct powering from a 10 V rail, reducing external component count. Verify that the required operating voltage range falls within the specified -35 V to -80 V limits for reliable performance.
Part Context
This component belongs to the ADM1075 family of hot swap controllers manufactured by Analog Devices. It is specifically engineered for managing power delivery in negative voltage environments, offering a compact solution for protecting sensitive electronics during board insertion and removal in active systems.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided source material. Consult official manufacturer documentation for potential cross-references or updated series replacements.
