LTC1646IGN#TRPBF

Hot Swap Controllers Overview

The LTC1646IGN#TRPBF is a dual hot-swap controller designed for Compact PCI applications requiring 3.3V and 5V supplies. It operates within an input voltage range of 2.7V to 7V and features two independent channels. The device supports programmable current limiting and includes integrated soft-start functionality to manage inrush currents during board insertion. It is housed in a 16-lead SSOP package and functions within a temperature range of -40°C to +85°C, drawing a typical operating supply current of 1.5mA.

Hot Swap Controllers Feature Summary

• Dual-channel architecture enables simultaneous power isolation for separate voltage rails
• Programmable current limit control allows precise protection settings via external components
• Integrated soft-start circuitry manages ramp-up rates to prevent bus disturbances

Hot Swap Controllers Applications

• Compact PCI hot-swap power supply isolation
• PCI Mezzanine Card (PMC) power management
• High-density server backplane power distribution

Hot Swap Controllers Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm tape-and-reel packaging versus tube variants. Ensure the component matches the required thermal grade and pinout configuration for your PCB layout. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and traceability before procurement.

Hot Swap Controllers Selection Notes

Select this controller when designing systems that require compliant hot-swap capabilities for Compact PCI or similar standards. Evaluate the need for dual independent channels versus single-channel alternatives based on power rail requirements. Consider the SSOP package constraints and ensure adequate thermal dissipation for the intended operating environment.
