LTC4218CDHC-12#TRPBF

Hot Swap Controllers Overview

The LTC4218CDHC-12#TRPBF is a dual ideal diode-OR and single hot swap controller manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.9V to 26.5V and features a 16-lead SSOP package. The device supports ATCA and MicroTCA standards, offering programmable auto-retry, current limiting, fault timeout, latch-off, overvoltage protection (OVP), and under-voltage lockout (UVLO). It consumes 1.6mA of operating supply current and functions reliably across an industrial temperature range of -40°C to +85°C.

Hot Swap Controllers Feature Summary

• Integrates dual ideal diode-OR functionality with a single hot swap controller for redundant power systems
• Supports ATCA and MicroTCA standards with comprehensive fault management including latch-off and auto-retry
• Provides precise current monitoring and adjustable current limiting for load protection

Hot Swap Controllers Applications

• Advanced Telecommunications Computing Architecture (ATCA) backplanes
• MicroTCA system implementations
• Redundant power distribution modules

Hot Swap Controllers Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when sourcing. Confirm the CDHC variant meets the required industrial temperature specifications. Ensure compatibility with existing board layouts for the 16-SSOP footprint. Cross-reference the manufacturer's latest datasheet revision to confirm pinout integrity before finalizing procurement orders.

Hot Swap Controllers Selection Notes

Select this component for designs requiring combined redundancy and hot swap capabilities in a compact form factor. The integrated dual ideal diode function simplifies power path management compared to discrete solutions. Consider the 16-SSOP package constraints for thermal performance and PCB space availability during the initial design phase.

Hot Swap Controllers Part Context

This part belongs to the LTC4218 family, which combines dual ideal diode-OR controllers with a single hot swap controller. It is designed for high-reliability applications such as telecommunications infrastructure where continuous operation and fault tolerance are critical requirements for system stability.
