LM25061  
Positive Low Voltage Power Limiting Hot Swap Controller  
General Description  
Features  
The LM25061 positive hot swap controller provides intelligent  
control of the power supply voltage to the load during insertion  
and removal of circuit cards from a live system backplane or  
other "hot" power sources. The LM25061 provides in-rush  
current control to limit system voltage droop and transients.  
The current limit and power dissipation in the external series  
pass N-Channel MOSFET are programmable, ensuring op-  
eration within the Safe Operating Area (SOA). The POWER  
GOOD output indicates when the output voltage exceeds a  
programmable threshold. The input under-voltage level and  
hysteresis are programmable, as well as the initial insertion  
delay time and fault detection time. The LM25061-1 latches  
off after a fault detection, while the LM25061-2 automatically  
restarts at a fixed duty cycle. The LM25061 is available in a  
10 pin MSOP package.  
Operating range: +2.9V to +17V  
In-rush current limit for safe board insertion into live power  
sources  
Programmable maximum power dissipation in the external  
pass device  
Adjustable current limit  
Circuit breaker function for severe over-current events  
Internal high side charge pump and gate driver for external  
N-channel MOSFET  
Adjustable under-voltage lockout (UVLO) and hysteresis  
Adjustable output voltage monitoring and hysteresis  
Initial insertion timer allows ringing and transients to  
subside after system connection  
Programmable fault timer avoids nuisance trips  
Active high open drain POWER GOOD output  
Available in latched fault and automatic restart versions  
Applications  
Server Backplane Systems  
Base Station Power Distribution Systems  
Solid State Circuit Breaker
