Supply Protection Controller  
DescripTion  
FeaTures  
The LTC®4365 protects applications where power supply  
input voltages may be too high, too low or even negative.  
It does this by controlling the gate voltages of a pair of  
external N-channel MOSFETs to ensure that the output  
stays within a safe operating range.The LTC4365 can  
withstand voltages between –40V and 60V and has an  
operating range of 2.5V to 34V, while consuming only  
125µA in normal operation.

Adjustable Undervoltage and Overvoltage  
Protection Range  
Two comparator inputs allow configuration of the over-  
voltage (OV) and undervoltage (UV) set points using an  
externalresistivedivider.Ashutdownpinprovidesexternal  
control for enabling and disabling the MOSFETs as well  
as placing the device in a low current shutdown state. A  
fault output provides status of the gate pin pulling low. A  
fault is indicated when the part is in shutdown or the input  
voltage is outside the UV and OV set points.

applicaTions  
The LTC4365 has a 36ms turn-on delay that debounces  
live connections and blocks 50Hz to 60Hz AC power. For  
fast recovery after faults, the LTC4365-1 has a reduced  
1ms turn-on delay.
