Positive High-Voltage, Hot-Swap Controllers  
General Description  
Features  
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).  
♦ Pin- and Function-Compatible with the LT1641-2  
(MAX5947B)  
♦ Provides Safe Hot Swap for +9V to +80V Power-  
Supply Range (MAX5947A/B/C)  
♦ Safe Board Insertion and Removal from Live  
Backplanes  
♦ Latched/Autoretry Management  
♦ Active-Low or Active-High Power-Good Output  
♦ Programmable Foldback Current Limiting  
♦ High-Side Drive for an External N-Channel MOSFET  
♦ Built-In Thermal Shutdown  
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).  
♦ Undervoltage Lockout (UVLO)  
♦ Overvoltage Protection  
♦ User-Programmable Supply Voltage  
Power-Up Rate  
Ordering Information  
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.
