Positive High-Voltage, Hot-Swap Controllers
General Description
The MAX5933A–MAX5933F/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 MAX5933A–MAX5933F 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°C to +85°C. These devices are
available in an 8-pin SO package.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
