Fe a t u re s  
The MAX4370 is a circuit-breaker IC designed to offer  
p rote c tion in hot-s wa p a p p lic a tions us ing Ma xim’s  
Dua lSp e e d /BiLe ve l™ d e te c tion. This c ontrolle r,  
designed to reside either on the backplane or on the  
removable card, is used to protect a system from start-  
up damage when a card or board is inserted into a rack  
with the main system power supply turned on. The  
c a rd ’s d is c ha rg e d filte r c a p a c itors p rovid e a low  
impedance that can momentarily cause the main power  
supply to collapse. The MAX4370 prevents this start-up  
condition by providing inrush current regulation during  
a programmable start-up period, allowing the system to  
stabilize safely. In addition, two on-chip comparators  
provide DualSpeed/BiLevel short-circuit protection and  
overcurrent protection during normal operation.  
♦ DualSpeed/BiLevel Protection During Normal  
Operation  
♦ Inrush Current Regulated at Start-Up  
♦ Resides Either on the Backplane or on the  
Removable Card  
♦ Programmable Start-Up Period and Response  
Time  
♦ Allows Safe Board Insertion and Removal from  
Live Backplane  
♦ Protection for +3V to +12V Single Supplies  
♦ Latched Off After Fault Condition  
♦ Status Output Pin  
The MAX4370 provides protection for a +3V to +12V  
single supply. An internal charge pump generates the  
controlled gate drive for an external N-channel MOS-  
FET power switch. The MAX4370 latches the switch off  
after a fault condition until an external reset signal  
clears the device. Other features include a status pin to  
indicate a fault condition, an adjustable overcurrent  
response time, and a power-on reset comparator.  
♦ Internal Charge Pump Generates Gate Drive for  
External N-Channel MOSFET
