Product Details
| DESCRIPTION The LTC®4252 negative voltage Hot SwapTM controller allows 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. FEATURES ■ Allows Safe Board Insertion and Removal from a Live –48V Backplane ■ Floating Topology Permits Very High Voltage Operation ■ Programmable Analog Current Limit With Circuit Breaker Timer ■ Fast Response Time Limits Peak Fault Current ■ Programmable Soft-Start Current Limit ■ Programmable Timer with Drain Voltage Accelerated Response ■ ±1% Undervoltage/Overvoltage Threshold Accuracy (LTC4252A) ■ Adjustable Undervoltage/Overvoltage Protection ■ LTC4252-1/LTC4252A-1: Latch Off After Fault ■ LTC4252-2: Automatic Retry After Fault ■ Available in 8-Pin and 10-Pin MSOP Packages APPLICATIONS ■ Hot Board Insertion ■ Electronic Circuit Breaker ■ –48V Distributed Power Systems ■ Negative Power Supply Control ■ Central Office Switching ■ High Availability Servers ■ ATCA |
