Overview
The ADM1170-1AUJZ-RL7 is a hot swap voltage controller designed for safe board insertion and removal from live backplanes. It operates within an input supply range of 2.7 V to 16.5 V and supports adjustable current limiting. The device features power-fail detection and auto-retry capabilities, ensuring robust protection during system faults. It functions reliably across an industrial temperature range of -40°C to +85°C with a typical operating supply current of 650 µA. Packaged in an 8-lead TSOT (UJ-8) surface-mount format, it integrates essential controls for managing inrush currents and overvoltage conditions in single-channel applications.
Feature Summary
- Enables safe hot insertion and removal of circuit boards from active backplanes
- Provides adjustable current limiting to protect against short circuits and overload conditions
- Integrates power-fail detection with automatic retry functionality for fault recovery
Applications
- Server and storage backplane card insertion management
- Industrial control system module protection
- Telecommunications equipment board handling
Procurement Notes
Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm the UJ-8 package variant matches your PCB footprint requirements. Ensure the component meets RoHS standards as specified by Analog Devices. Cross-reference the datasheet revision to confirm compatibility with your system design constraints before finalizing procurement orders.
Selection Notes
Select this controller for applications requiring precise inrush current management and thermal protection. The adjustable current limit allows customization for different load profiles. Verify that the 16.5 V maximum rating aligns with your bus voltage. Consider the TSOT-8 package size for space-constrained designs requiring surface-mount integration.
Part Context
This component belongs to the ADM1170 series of hot swap controllers from Analog Devices. It serves as a critical interface between the main bus and peripheral cards, preventing damage during plug-in events. The part is distinct from the ADM1171 and ADM1172 variants which may offer different channel counts or feature sets.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Users should consult official Analog Devices resources for qualified alternatives.
