MAX5902LCETT+T

Hot Swap Controllers Overview

The MAX5902LCETT+T is a hot-swap voltage controller from the Simple Swapper family, designed for safe insertion into live backplanes. It operates within a supply voltage range of +9V to +72V and features an adjustable current limit function. The device provides overcurrent protection with a circuit-breaker capability while disabling this function during startup to manage inrush current. It utilizes a SOT-23-6 surface-mount package and supports an operating temperature range from -40°C to +85°C.

Hot Swap Controllers Feature Summary

• Eliminates external components except the p-channel MOSFET for simplified hot-swap implementation
• Provides adjustable current limiting and circuit-breaker functionality for overcurrent protection
• Disables circuit-breaker function during startup to safely handle load inrush current

Hot Swap Controllers Applications

• Network equipment power distribution
• Live backplane insertion systems
• Power-supply sequencing applications

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'LCETT' against official Analog Devices documentation to confirm pinout and thermal characteristics. Confirm RoHS compliance status and check for obsolescence notices or lifecycle changes directly from manufacturer resources before finalizing procurement plans.

Hot Swap Controllers Selection Notes

Select this component when a compact solution is required for high-voltage hot-swap applications up to 72V. Ensure the design accommodates an external p-channel MOSFET as the internal switch is not included. Verify that the adjustable current limit meets the specific load requirements for the target application.

Hot Swap Controllers Part Context

This part belongs to the MAX5902/MAX5903 series of Simple Swapper hot-swap controllers. These devices are engineered to prevent glitches on power-supply rails during card insertion. The series focuses on minimizing external component count while providing robust protection against overcurrent conditions in demanding industrial and networking environments.

Hot Swap Controllers Replacement Considerations

Consult official substitution guides for compatible alternatives within the MAX5902 series. Verify package compatibility and electrical specifications before replacing.
