Overview
The ADM1172-1AUJZ-RL7 is a single-channel hot-swap voltage controller manufactured by Analog Devices Inc. It operates within an input voltage range of 2.7 V to 16.5 V and features adjustable current limiting. The device includes power failure detection capabilities and supports auto-retry functionality for robust system management. Designed for surface-mount installation, it utilizes a TSOT-8 package and maintains a typical operating supply current of 800 uA. The component functions reliably across an industrial temperature range from -40°C to +85°C.
Feature Summary
- Integrates positive hot-swap control with power fail indication (PFI/PFO) and auto-retry logic
- Provides adjustable current limiting to protect downstream circuits during insertion events
- Features dedicated enable input and gate pin output for driving external field-effect transistors
Applications
- Server backplane card insertion protection
- Industrial I/O module hot-plugging interfaces
- Peripheral board power sequencing in embedded systems
Procurement Notes
Verify the specific suffix RL7 against official Analog Devices documentation to confirm reel packaging specifications. Confirm RoHS compliance status through the manufacturer's environmental declaration. Ensure the TSOT-8 footprint matches your PCB layout requirements before finalizing procurement decisions.
Selection Notes
Select this component when designing systems requiring controlled power ramp-up during hot-swap operations. The adjustable current limit allows customization for various load profiles. Consider the low quiescent current for battery-backed or energy-efficient applications. Verify that the 16.5 V maximum input rating aligns with your bus voltage levels.
Part Context
This part belongs to the ADM1172 series of hot-swap controllers. It is distinct from linear regulators like the ADP170 or voltage references such as the ADR127 found in similar catalogs. The device specifically addresses power management challenges related to safe insertion and removal of live circuit boards without causing voltage sags or overcurrent faults.
Replacement Considerations
Consult official Analog Devices substitution guides for verified alternatives. Generic hot-swap controllers may lack the specific PFI/PFO and auto-retry integration. Do not assume pin compatibility with other TSOT-8 packages without detailed datasheet comparison.
