Hot Swap Controllers datasheet and documents for LTC4287AUK#PBF

LTC4287AUK#PBF

Hot Swap Controllers Overview

The LTC4287AUK#PBF is a high-power positive hot swap controller designed for safe board insertion and removal from live backplanes. It features dual-gate drivers and configurable multimode startup sequencing to optimize MOSFET safe operating area across various power levels. The device integrates an SMBus interface with onboard analog-to-digital converters for monitoring current, voltage, power, energy, temperature, and fault status. It provides adjustable current limiting with foldback, circuit breaker timer protection against overstress, and BlackBox fault capturing capabilities.

Hot Swap Controllers Feature Summary

Dual-gate driver architecture optimized for high-power applications
Configurable multimode startup sequencing for MOSFET safe operating area management
Integrated analog-to-digital converters for real-time system parameter monitoring
BlackBox fault capturing and EEPROM configuration support

Hot Swap Controllers Applications

Server blade insertion and removal in live backplane systems
High-power peripheral card hot swapping
