LM5069  
Positive High Voltage Hot Swap / Inrush Current Controller  
with Power Limiting  
General Description  
The LM5069 positive hot swap controller provides intelligent  
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 over-voltage lockout (OVLO) and hysteresis  
control of the power supply connections during insertion and  
removal of circuit cards from a live system backplane or other  
"hot" power sources. The LM5069 provides in-rush current  
control to limit system voltage droop and transients. The cur-  
rent limit and power dissipation in the external series pass N-  
Channel MOSFET are programmable, ensuring operation  
within the Safe Operating Area (SOA). The POWER GOOD  
output indicates when the output voltage is within 1.25V of the  
input voltage. The input under-voltage and over-voltage lock-  
out levels and hysteresis are programmable, as well as the  
initial insertion delay time and fault detection time. The  
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  
LM5069-1 latches off after a fault detection, while the Applications  
LM5069-2 automatically restarts at a fixed duty cycle. The  
LM5069 is available in a 10 pin MSOP package.  
Server Backplane Systems  
Base Station Power Distribution Systems  
Solid State Circuit Breaker  
Features  
24V/48V Industrial Systems  
Wide operating range: +9V to +80V  
In-rush current limit for safe board insertion into live power  
sources  
Package  
MSOP-10  
Programmable maximum power dissipation in the external  
pass device
