General Description
The MAX8533 is a single-port, 12V, Infiniband
TM
-compli-
ant (IB) versatile hot-swap controller. The device can be
implemented in both IB Class I (nonisolated) and Class II
(isolated) power-topology applications. Additionally, the
MAX8533 can be used as a reliable power controller on
hot-swappable blade servers, RAID cards, and network
switches or routers that are powered from a 12V bus.
The MAX8533 integrates several features that allow reli-
able insertion and removal of the circuit card, as well as
real-time monitoring of abnormal occurrences. The
MAX8533 allows for an adjustable soft-start ramp during
turn-on of the input voltage, while providing overcurrent
protection. It also provides accurate and consistent cur-
rent-regulated outputs for a programmable period of time
to latch off and soft-start in the presence of overcurrent
conditions (OC). Additionally, it provides a second level
of severe overcurrent (SOC) protection by responding to
a dead short in 100ns. The MAX8533 also includes
adjustable overvoltage protection.
The MAX8533 incorporates undervoltage lockout
(UVLO) and a power-good (POK) signal to the DC-to-
DC converters to confirm the status of output voltage
rails during operation. Two enable inputs EN (logic
enable) and LPEN (local power enable) provide flexible
sequencing. The MAX8533 is specified across the
extended temperature range and has an absolute maxi-
mum rating of 16V to withstand inductive kickback dur-
ing board removal.
The MAX8533 is available in the space-saving 10-pin
礛AX package.
