ADM1070ART-REEL7

Overview

The ADM1070ART-REEL7 is a hot swap voltage controller manufactured by Analog Devices Inc., designed for safe insertion and removal of live circuit boards. It operates within a supply voltage range of -80 V to -18 V and features programmable current limiting. The device monitors power failure and functions reliably across an operating temperature range of -40°C to +85°C. It draws a typical quiescent current of 850 uA and is housed in a compact SOT-23-6 surface-mount package, facilitating integration into space-constrained power management applications.

Feature Summary

• Integrates programmable current limiting for controlled power-up sequences
• Includes dedicated power fail detection logic for system protection
• Supports safe hot swapping of circuits under negative voltage conditions

Applications

• Server blade insertion systems
• Telecommunications backplane power distribution
• Industrial control board hot-swap interfaces

Procurement Notes

Verify the exact suffix against official Analog Devices documentation, as REEL7 indicates specific tape-and-reel packaging. Confirm availability status directly with authorized distributors, as this component may be subject to limited supply or discontinuation notices. Ensure the ordering part number matches the required package variant and temperature grade specified in the latest datasheet revision.

Selection Notes

Select this component when designing systems requiring robust protection during live board insertion. The negative voltage operation capability distinguishes it from standard positive-rail controllers. Evaluate the programmable current limit settings against the load requirements to ensure adequate surge handling without nuisance tripping during startup phases.

Part Context

This part belongs to the ADM1070 series of hot swap controllers from Analog Devices. These devices are engineered to manage the inrush currents associated with connecting powered loads to active buses. The ART designation typically denotes the specific temperature grade and package style within the broader product family.

Replacement Considerations

Consult the official Analog Devices replacement guide for verified cross-reference part numbers. Do not assume functional compatibility with other hot swap controllers due to differences in voltage ratings and pin configurations.
