MAX4271, MAX4272, MAX4273 3V To 12V, Current-Limiting, Hot Swap Controllers With Autoretry, DualSpeed/BiLevel Fault Protection

The MAX4271 MAX4272 MAX4273 comprise a complete family of integrated 3V to 12V hot-swap controllers. They allow the safe insertion and removal of circuit cards into live Backplanes
The discharged Filter capacitors of the circuit card provide a low impedance to the live Backplane High in-rush currents from the Backplane to the circuit card CAN burn up connectors and components, or momentarily collapse the Backplane power supply leading to a system reset. This family of hot-swap controllers prevents such problems by regulating the current to a preset limit when the board is plugged in, allowing the system to stabilize safely. After the startup cycle is completed, two on-chip Comparators provide DualSpeed/BiLevel" protection against short circuits, load glitches, and overcurrent conditions. In the event of a fault condition, the load is disconnected. Fault recovery is handled by unlatching MAX4271 , autoretry MAX4272 , or programmed MAX4273 methods.
The MAX4271 family includes many integrated features that reduce component count and design time. An on-board Charge Pump provides the Gate drive for a low-cost, external n-FET. Integrated features like startup current regulation and current glitch protection eliminate external Timing resistors and capacitors. Also featured are an open-drain status output to indicate a fault condition, and an adjustable overcurrent response time.
The MAX4271 (latched fault protection) and MAX4272 (autoretry fault protection) come in 8-pin SO packages. The MAX4273 (full function) comes in the space-saving 16-pin QSOP package and 16-pin SO package. All parts are specified across the extended temperature range, and have an absolute maximum rating of 15V to provide extra protection against inductive kickback during board removal.
