LTC4249AV-1#PBF

Overview

The LTC4249AV-1#PBF is a dual hot-swap controller from Analog Devices, designed for -48V telecom and industrial applications. It supports two independent channels with integrated current monitoring and protection. The device operates within a supply voltage range of 3V to 60V and functions across an extended temperature range of -40°C to +125°C. Packaged in a 16-lead SSOP, it provides precise control over power-up sequencing and fault conditions.

Feature Summary

• Dual-channel architecture for independent hot-swap control
• Integrated current sensing and limit management
• Supports negative voltage systems typical in telecom infrastructure

Applications

• -48V telecommunications equipment
• Industrial backplane power distribution
• Server and networking hardware input stages

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to limited availability status. Confirm package integrity and moisture sensitivity handling requirements upon receipt. Ensure compatibility with existing board design thermal and electrical constraints before finalizing procurement orders.

Selection Notes

Select this component when dual-channel protection is required for negative voltage rails. Evaluate channel isolation needs and current threshold settings against system load profiles. Consider the SSOP package dimensions for PCB layout constraints and thermal dissipation requirements relative to adjacent components.

Part Context

Part of the LTC4249 series focusing on dual-channel hot-swap solutions. Complements single-channel variants like the LTC4240 for higher density designs. Fits within Analog Devices' portfolio of power management ICs targeting robust infrastructure protection.
