-100V SOT23 Simple Swapper Hot-Swap  
Controllers  
General Description  
Features  
The MAX5900/MAX5901 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  
-100V and provide the simplest hot-swap solution by  
eliminating all external components except an external  
N-channel MOSFET.  
o Wide -9V to -100V Operation  
o Requires No External Sense Resistor  
o Drives External N-Channel MOSFET  
o Limits Inrush Current  
o Circuit Breaker Function  
The MAX5900/MAX5901 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 MAX5900/MAX5901 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  
MAX5900/MAX5901 provide overcurrent protection by  
monitoring the voltage drop across the external MOS-  
FET’s on-resistance.  
o Less than 1mA Quiescent Current  
o ON/OFF Input Permits Load Power-Supply  
Control and Sequencing  
o Adjustable Undervoltage Lockout  
o Power-Good Output with 100V Rating  
o Latching or Automatic Retry Fault Management  
o Thermal Shutdown Helps Protect the External  
The MAX5900/MAX5901 include an undervoltage lock-  
out (UVLO) function, ON/OFF control input, and a  
power-good status output, PGOOD (MAX5900) or  
PGOOD (MAX5901). 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 MAX5900/MAX5901 offer latched or auto-retry fault  
management and are available with 200mV, 300mV or  
400mV circuit breaker thresholds. Both the MAX5900  
and MAX5901 are available in small SOT23 packages,  
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.
