ADM4210-2AUJZ-RL7

Overview

The ADM4210-2AUJZ-RL7 is a hot-swap controller manufactured by Analog Devices Inc., designed for safe insertion and removal of live circuit boards. It operates within an ambient temperature range of -40°C to +85°C and is housed in a compact 6-Lead TSOT package with the UJ-6 marking. This device provides latched fault protection and under-voltage lockout (UVLO) capabilities, ensuring robust system integrity during power-up and fault conditions without requiring an internal switch.

Feature Summary

• Provides latched fault protection to maintain system safety during over-current or short-circuit events until manually reset.
• Integrates under-voltage lockout (UVLO) to prevent operation when supply voltage is insufficient for reliable control.

Applications

• Hot-swappable peripheral card insertion systems
• PCI/PCI-X backplane power management
• General-purpose board insertion protection

Procurement Notes

Verify the complete part number including suffixes such as -RL7 for reel packaging configuration. Confirm the operating temperature grade corresponds to industrial specifications (-40°C to +85°C). Ensure the TSOT-6 package variant matches the PCB footprint requirements. Cross-reference the manufacturer's latest datasheet for any updates to pin definitions or electrical characteristics prior to final design approval.

Selection Notes

Select this component when active current limiting and latched fault handling are required for hot-swap applications. The absence of an internal switch necessitates an external pass transistor or FET. Consider the thermal performance of the external switch and the TSOT-6 package limitations. Verify that the UVLO thresholds align with the system's power rail stability requirements during startup sequences.

Part Context

This component belongs to the ADM4210 series of hot-swap controllers from Analog Devices. It is specifically engineered for protecting electronic circuits during live insertion. The device complements other power management solutions by providing precise control over inrush current and fault states, distinct from simple fuses or basic circuit breakers.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing gate drive circuits if replacing similar hot-swap controllers from other manufacturers.

FAQ

Does the ADM4210-2AUJZ-RL7 include an internal power switch?

No, the device does not contain an internal switch; it requires an external N-channel MOSFET to handle the load current.

What type of fault protection does this controller offer?

It offers latched fault protection, which disables the output and holds it off until the fault condition is cleared and the device is reset.
