ADM1276-3ACPZ-RL

Overview

The ADM1276-3ACPZ-RL is a hot swap controller and monitor designed to protect circuit boards and backplanes from inrush currents and overvoltage faults. It enables safe insertion or removal of cards into live backplanes. The device operates within a supply voltage range of 2.95V to 20V and supports an operating temperature range of -40°C to +85°C. It features a 20-pin LFCSP package with an exposed pad for surface mount installation.

Feature Summary

• Provides protection against inrush currents and overvoltage faults during board insertion
• Enables safe hot swapping of circuit boards into live backplanes
• Integrates monitoring capabilities for system power integrity

Applications

• Server and storage backplane protection
• Telecommunications equipment card insertion
• Industrial control system module replacement

Procurement Notes

Verify the specific suffix '-3' indicates the correct pinout and configuration variant required for your design, as Analog Devices often uses suffixes to denote package or thermal options. Confirm the 20-LFCSP package dimensions match your PCB footprint. Ensure the 2.95V to 20V input range aligns with your system's available rail voltages before finalizing procurement.

Selection Notes

Select this component when active hot swap capability is required for 2.95V to 20V systems. It is suitable for applications needing integrated current limiting and fault monitoring without external discrete components. Consider the 20-LFCSP package size constraints and thermal dissipation requirements for high-current applications.
