3V to 12V Current-Limiting Hot-Swap Controllers
with Autoretry, DualSpeed/BiLevel Fault Protection
General Description
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.
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.
The MAX4271 family includes many integrated features
Features
? 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
? 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

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.
