Overview
The ADM1170-2AUJZ-RL7 is a dual-channel hot swap voltage controller manufactured by Analog Devices Inc. It supports an input supply voltage range from 1.6 V to 16.5 V and features adjustable current limiting for each channel. The device operates within a temperature range of -40°C to +85°C and is housed in a TSOT-8 surface-mount package. Designed for safe insertion and removal of boards from live backplanes, it integrates power-fail detection and auto-retry functionality to ensure system reliability during fault conditions.
Feature Summary
- Dual-channel architecture enabling independent control of two hot swap paths
- Adjustable current limiting for precise protection against overcurrent events
- Integrated power-fail detection to monitor bus voltage integrity
- Auto-retry mechanism to automatically recover from transient faults
Applications
- Safe insertion and removal of circuit boards from live backplanes
- Protection of peripheral cards in industrial computing systems
- Power distribution management in telecommunications equipment
- Hot swap interfaces in server and storage subsystems
Procurement Notes
Verify the specific suffix RL7 indicates reel packaging configuration when sourcing. Confirm the dual-channel variant matches system requirements compared to single-channel alternatives like the ADM1170-1AUJZ. Ensure compatibility with the target board's thermal dissipation capabilities given the TSOT-8 package constraints. Cross-reference the manufacturer datasheet for exact pinout and electrical characteristics prior to integration.
Selection Notes
Select this component when dual independent hot swap channels are required within a compact footprint. Compare against the ADM1171 series if higher performance or additional features are needed. Evaluate the input voltage range suitability for the specific bus architecture. Consider the TSOT-8 package size constraints relative to available PCB real estate and thermal management strategies for the application environment.
Part Context
This part belongs to the ADM117x family of hot swap controllers from Analog Devices. It shares functional similarities with the ADM1170-1AUJZ but provides dual channels instead of one. The series is designed for robust power management in environments requiring frequent board maintenance. It complements other PMIC solutions by handling high-inrush currents safely without disrupting the main power bus.
Replacement Considerations
The ADM1170-1AUJZ-RL7 serves as a single-channel alternative within the same family. For dual-channel applications requiring different specifications, the ADM1172-2AUJZ-RL7 may be considered. Verify pin-to-pin compatibility and electrical parameter alignment before substituting any component in existing designs.
