LTC4253/LTC4253A  
–48V Hot Swap Controllers  
with Sequencer  
FEATURES  
DESCRIPTION  
The LTC®4253/LTC4253A negative voltage Hot Swap™  
controllersallowaboardtobesafelyinsertedandremoved  
fromalivebackplane.Outputcurrentiscontrolledbythree  
stages of current-limiting: a timed circuit breaker, active  
current limiting and a fast feedforward path that limits  
peak current under worst-case catastrophic fault condi-  
tions. The LTC4253/LTC4253A latch off after a circuit fault.

n
Adjustable Undervoltage/Overvoltage Protection  
Adjustable undervoltage and overvoltage detectors dis-  
connect the load whenever the input supply exceeds the  
desired operating range. The LTC4253/LTC4253A’s supply  
input is shunt-regulated, allowing safe operation with very  
high supply voltages. A multifunction timer delays initial  
start-up and controls the circuit breaker’s response time.  
The circuit breaker’s response time can be accelerated  
by sensing excessive MOSFET drain voltage, keeping the  
MOSFETwithinitssafeoperatingarea(SOA).Anadjustable

Threepowergoodoutputsaresequencedbyanadjustable  
timer and two ENABLE inputs to enable external power  
modules at start-up or disable them if the circuit breaker  
trips. The LTC4253A features tight ±±1 undervoltage/  
overvoltage threshold accuracy. The LTC4253/LTC4253A  
are available in a ±6-pin SSOP.
