LTC4414  
36V, Low Loss PowerPathTM  
Controller for Large PFETs  
U
FEATURES  
DESCRIPTIO  
The LTC®4414 controls an external P-channel MOSFET to  
create a near ideal diode function for power switchover.  
This permits highly efficient OR’ing of multiple power  
sourcesforextendedbatterylifeandlowself-heating.When  
conducting, the voltage drop across the MOSFET is typi-  
cally20mV.Forapplicationswithawalladapterorotheraux-  
iliarypowersource,theloadisautomaticallydisconnected  
from the battery when the auxiliary source is connected.  
Two or more LTC4414s may be interconnected to allow  
switchover between multiple batteries or charging of mul-  
tiple batteries from a single charger.

■
Space Saving 8-Lead MSOP Package  
The wide supply operating range supports operation from  
one to eight Li-Ion cells in series. The low quiescent  
current (30µA typical) is independent of the load current.  
The gate driver includes an internal voltage clamp for  
MOSFET protection.

APPLICATIO S  
■
High Current Power Path Switch  
■
Industrial and Automotive Applications  
The STAT pin can be used to enable an auxiliary P-channel  
MOSFET power switch when an auxiliary supply is  
detected. This pin may also be used to indicate to a micro-  
controller that an auxiliary supply is connected. The con-  
trol (CTL) input enables the user to force the primary  
MOSFET off and the STAT pin low.
