LT4220CGN#PBF

Hot Swap Controllers Overview

The LT4220CGN#PBF is a dual-channel hot swap voltage controller manufactured by Analog Devices Inc. It operates within an input voltage range of 2.7 V to 16.5 V and features adjustable current limiting for precise power-up control. The device supports two independent channels, each capable of managing load connections with integrated protection mechanisms. Designed for surface-mount applications, it utilizes an SSOP-16 package. The component functions effectively across a standard commercial temperature range from 0°C to +70°C, drawing a typical operating supply current of 2.7 mA.

Hot Swap Controllers Feature Summary

• Dual-channel architecture enables independent management of two separate loads or buses
• Adjustable current limiting allows customization of inrush current and fault protection thresholds
• Integrated soft-start functionality controls the rate of output voltage rise to prevent system disturbances

Hot Swap Controllers Applications

• Server and storage backplane power distribution
• Industrial equipment hot-pluggable I/O modules
• Telecommunications infrastructure card insertion systems

Hot Swap Controllers Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to confirm pinout compatibility and thermal characteristics. Ensure that the SSOP-16 footprint matches the target PCB layout dimensions precisely. Confirm RoHS compliance status through the latest datasheet revision notes before finalizing procurement specifications.

Hot Swap Controllers Selection Notes

Evaluate the required channel count to determine if the dual-channel configuration offers necessary space efficiency compared to single-channel alternatives. Assess the maximum input voltage requirements to ensure the 16.5 V limit accommodates the highest expected bus voltage with adequate margin. Consider the adjustable current limit feature for optimizing protection settings relative to the connected load specifications.
