General Description
The MAX5933AMAX5933F/MAX5947A/B/C fully integrat-
ed hot-swap controllers for +9V to +80V positive supply
rails (MAX5947A/B/C), allow for the safe insertion and
removal of circuit cards into live backplanes without caus-
ing glitches on the backplane power-supply rail. The
MAX5947B is pin- and function-compatible with the
LT1641-2. The other devices offer added features such
as a choice of active-high or active-low power-good out-
puts (PWRGD/PWRGD), latched/autoretry fault manage-
ment, and autoretry duty-cycle options of 3.75% or 0.94%
(see the Selector Guide).
The MAX5933AMAX5933F are available with a default
undervoltage lockout threshold of +31V and operate over
a supply voltage range of +33V to +80V. The
MAX5947A/B/C are available with a default undervoltage
of +8.3V. All devices feature a programmable analog
foldback current limit. If the device remains in current limit
for more than a programmable time, the external
n-channel MOSFET is either latched off (MAX5933A/
MAX5933C/MAX5947A) or is set to automatically restart
after a timeout delay (MAX5933B/MAX5933D/MAX5933E/
MAX5933F/MAX5947B/MAX5947C).
The MAX5933_ and MAX5947_ operate in the extended
temperature range of -40癈 to +85癈. These devices are
available in an 8-pin SO package.
