+72V SOT23 Simple Swapper Hot-Swap  
Controllers  
General Description  
Features  
The MAX5902/MAX5903 are SOT23 hot-swap con-  
trollers that allow a circuit card to be safely hot plugged  
into a live backplane without causing a glitch on the  
power-supply rail. These devices operate from +9V to  
+72V and provide the simplest hot-swap solution by  
eliminating all external components except the external  
P-channel MOSFET.  
o Wide +9V to +72V Operation  
o Requires No External Sense Resistor  
o Drives External P-Channel MOSFET  
o Limits Inrush Current  
o Circuit Breaker Function  
The MAX5902/MAX5903 limit the inrush current to the  
load and provide a circuit breaker function for overcur-  
rent protection. During startup the circuit breaker func-  
tion is disabled and the MAX5902/MAX5903 limit the  
inrush current by gradually turning on the external  
MOSFET. Once the external MOSFET is fully enhanced,  
the circuit breaker function is enabled and the  
MAX5902/MAX5903 provide overcurrent protection by  
monitoring the voltage drop across the external MOS-  
FET’s on-resistance.  
o Less than 2mA Quiescent Current  
o ON/OFF Input Permits Load Power-Supply  
Control and Sequencing  
o Adjustable Undervoltage Lockout  
o Power-Good Output with +72V Rating  
o Latching or Automatic Retry Fault Management  
o Thermal Shutdown Helps Protect the External  
The MAX5902/MAX5903 include an undervoltage lock-  
out (UVLO) function, ON/OFF control input and a  
power-good status output, PGOOD (MAX5902) or  
PGOOD (MAX5903). A built in thermal shutdown fea-  
ture is also included to protect the external MOSFET in  
case of overheating.

o Space-Saving SOT23-6 Package  
Ordering Information  
The MAX5902/MAX5903 offer latched or auto-retry fault  
management and are available with 300mV, 400mV or  
500mV circuit breaker thresholds. Both the MAX5902  
and MAX5903 are available in a small SOT23 package,  
and are specified for the extended -40°C to +85°C tem-  
perature range. For specific ordering information refer  
to the selector guide at the end of the data sheet.
