LTC4217CDHC#PBF

Hot Swap Controllers Overview

The LTC4217CDHC#PBF is a single-channel hot swap voltage controller manufactured by Analog Devices Inc. It features an internal N-channel MOSFET switch rated for 2A continuous load current. The device supports input supply voltages from 2.9V to 26.5V and operates within a commercial temperature range of 0°C to +70°C. Key electrical specifications include a quiescent supply current of 1.6mA. The component is housed in a 16-lead DFN (5x3mm) package with an exposed thermal pad, designed for surface-mount installation.

Hot Swap Controllers Feature Summary

• Integrates an internal high-side N-channel power switch for compact board-level implementation
• Provides dual-level overcurrent protection combining instantaneous analog limiting with adjustable response time circuit breaker functionality
• Features programmable soft-start capability to control inrush current during startup
• Includes comprehensive fault management with automatic retry, lockout, and timeout mechanisms

Hot Swap Controllers Applications

• General-purpose hot swap applications requiring safe insertion and removal from live backplanes
• Power distribution systems utilizing positive low voltage supplies
• Industrial equipment requiring robust overcurrent and thermal protection

Hot Swap Controllers Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm the exact package type and tape-and-reel versus tube configuration. Confirm that the operating temperature range aligns with the commercial grade specification required for the target application environment. Ensure compatibility with the intended input voltage levels before finalizing procurement.

Hot Swap Controllers Selection Notes

Select this component when a single-channel solution with integrated switching capability is required for low-voltage hot swap applications. Consider the 2A current rating and 26.5V maximum input voltage limits relative to system requirements. Evaluate the need for internal versus external switching based on cost and space constraints compared to controllers requiring external MOSFETs.

Hot Swap Controllers Part Context

This part belongs to the LTC4217 series of hot swap controllers from Analog Devices. The series focuses on providing complete power management solutions for board insertion applications. The CDHC variant specifically denotes the commercial temperature grade and the 16-lead DFN package format, distinguishing it from industrial grade or alternative packaging options within the same functional family.

Hot Swap Controllers Replacement Considerations

Consult official Analog Devices substitution guides for verified alternatives. Cross-reference pinouts and electrical characteristics carefully when considering generic hot swap controllers.
