LTC4282CUH#PBF

Hot Swap Controllers Overview

The LTC4282CUH#PBF is a single-channel hot swap controller manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.9 V to 33 V and features an I²C interface for configuration. The device provides overvoltage protection (OVP), undervoltage lockout (UVLO), and programmable current limiting. It is housed in a 32-WFQFN package with exposed pads, suitable for surface mount installation across an operating temperature range of -40°C to 85°C.

Hot Swap Controllers Feature Summary

• Integrates I²C digital interface for precise control and monitoring
• Provides hardware-based overvoltage protection and undervoltage lockout
• Features programmable current limiting for safe load insertion

Hot Swap Controllers Applications

• General purpose hot swap applications
• Peripheral board insertion systems
• Power distribution units requiring controlled power-up

Hot Swap Controllers Procurement Notes

Verify the specific suffix 'CUH' confirms the commercial temperature grade (-40°C to 85°C) and QFN-32 package variant. Confirm RoHS compliance status via the official datasheet before integration. Ensure I²C address settings match system requirements. Check for any recent product change notifications affecting pinout or electrical characteristics.

Hot Swap Controllers Selection Notes

Select this component when a single-channel solution with digital I²C control is required for high-current hot swap scenarios. It is appropriate for systems needing precise fault monitoring and programmable ramp rates. Consider thermal performance in the QFN-32 package during PCB layout. Verify input voltage compatibility with the 2.9 V to 33 V operational range.

Hot Swap Controllers Part Context

This part belongs to the LTC4282 family of hot swap controllers designed for managing power insertion into live backplanes. It serves as a critical interface between the power source and the load, preventing inrush currents and short circuits. The device complements other PMIC solutions by offering dedicated channel protection with digital configurability.
