FEATURES  
DESCRIPTIO  
The LTC®1645 is a 2-channel Hot SwapTM controller that  
allows a board to be safely inserted and removed from a  
livebackplane. UsingexternalN-channelpasstransistors,  
the supply voltages can be ramped at a programmable  
rate. Two high side switch drivers control the N-channel  
gates for supply voltages ranging from 1.2V to 12V. The  
two channels can be set to ramp up and down separately,  
ortheycanbeprogrammedtoriseandfallsimultaneously,  
ensuring power supply tracking at the two outputs.  
Allows Safe Board Insertion and Removal from a  
Live Backplane  
Programmable Power Supply Sequencing  
Programmable Electronic Circuit Breaker  
User-Programmable Supply Voltage Power-Up and  
Power-Down Rate  
High Side Drivers for External N-Channel FETs  
Controls Supply Voltages from 1.2V to 12V  
Ensures Proper Power-Up Behavior  
Undervoltage Lockout  
Programmable electronic circuit breakers protect against  
shorts at either output. The RESET output can be used to  
generate a system reset when a supply voltage falls below  
a user-programmed voltage. An additional spare com-  
parator is available for monitoring a second supply  
voltage.  
Glitch Filter Protects Against Spurious RESET Signals
