LTC4244IGN#PBF

Hot Swap Controllers Overview

The LTC4244IGN#PBF is a hot swap controller designed for CompactPCI applications. It features four channels with internal switches for both high-side and low-side control. The device supports supply voltages of 3.3V, 5V, and ±12V. Key programmable features include current limit and fault timeout settings. It operates within an industrial temperature range of -40°C to 85°C.

Hot Swap Controllers Feature Summary

• Integrates four independent channels with internal power switches for comprehensive board protection.
• Provides latched fault handling and thermal limiting to ensure safe operation during abnormal conditions.
• Includes under-voltage lockout (UVLO) mechanisms to prevent unreliable startup or operation.

Hot Swap Controllers Applications

• CompactPCI system backplanes
• Industrial server boards requiring hot insertion support
• Telecommunications equipment with multiple voltage rails

Hot Swap Controllers Procurement Notes

Verify the specific suffix against official Analog Devices documentation to confirm pinout and feature set variations. Ensure compatibility with your target supply voltage profile, as the device supports 3.3V, 5V, and ±12V systems. Confirm that the SSOP-28 package meets your PCB layout constraints before finalizing procurement orders.

Hot Swap Controllers Selection Notes

Select this component when designing systems requiring multi-channel hot swap protection for CompactPCI architectures. It is suitable for applications needing integrated current limiting and fault management without external discrete components. Consider the operating temperature range and supply voltage requirements to ensure alignment with your system's environmental and electrical specifications.
