Overview
MAX4271/MAX4272/MAX4273 19-1694; Rev 2; 12/07 EVAALVUAAILTAIOBNLEKIT 3V to 12V Current-Limiting Hot-Swap Controllers with Autoretry, DualSpeed/BiLevel Fault Protection General Description 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 inrush 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.
