3V to 12V Current-Limiting Hot-Swap Controllers  
with Autoretry, DualSpeed/BiLevel Fault Protection  
General Description  
Features  
The MAX4271/MAX4272/MAX4273 comprise a com-  
plete family of integrated 3V to 12V hot-swap con-  
trollers. They allow the safe insertion and removal of  
circuit cards into live backplanes.  
♦ Provide Safe Hot Swap for +3V to +12V Power  
Supplies with Few External Components  
♦ Unique Current Regulation Architecture  
Minimizes n-FET Linear Mode Duration  
♦ Autoretry Feature (MAX4272/MAX4273)  
♦ DualSpeed/BiLevel Current Limit Protects Against  
Current Glitches and Short Circuits  
The discharged filter capacitors of the circuit card pro-  
vide 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 sys-  
tem 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 pro-  
grammed (MAX4273) methods.  
♦ Power-On RESET (MAX4273)  
♦ 15V Absolute Maximum Rating Protects Against  
Inductive Kickbacks During Board Removal  
♦ Internal Charge Pump Generates Gate Drive for  
External n-MOSFET  
♦ Status Output Pin Indicates Fault/Safe Condition  
♦ Space-Saving 8-Pin SO, 16-Pin QSOP Packages  
________________________Applications  
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 condi-  
tion, and an adjustable overcurrent response time.

Ordering Information  
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 dur-  
ing board removal.
