LTC4251 Overview
Description
The LTC®4251/LTC4251-1/LTC4251-2 negative voltage Hot Swap™ controllers allow a board to be safely inserted and removed from a live backplane. Output current is controlled by three stages of current limiting: a timed circuit breaker, active current limiting and a fast feedforward path that limits peak current under worst-case catastrophic fault conditions.
Key Features
- Floating Topology Permits Very High Voltage Operation
- Programmable Analog Current Limit with Circuit Breaker Timer
- Fast Response Time Limits Peak Fault Current
- Programmable Timer
- Programmable Undervoltage/Overvoltage Protection
- Low Profile (1mm) ThinSOT™ Package
