36V, Low Loss Dual
PowerPath Controllers for
Large PFETs
The LTC4416/LTC4416-1 control two sets of external
P-channelMOSFETstocreatetwonearidealdiodefunctions
forpowerswitchovercircuits.Thispermitshighlyefficient
OR’ing of multiple power sources for extended battery life
and low self heating. When conducting, the voltage drop
acrosstheMOSFETistypically25mV.Forapplicationswith
a wall adapter or other auxiliary power source, the load is
automaticallydisconnectedfromthebatterywhentheaux-
iliarysourceisconnected.
The LTC4416 integrates two interconnected PowerPathTM
controllers with soft switchover control. The “soft-off”
switchover permits the users to transfer between two dis-
similar voltages without excessive voltage undershoot (or
VDROOP)intheoutputsupply.TheLTC4416/LTC4416-1also
containa“fast-on”featurethatdramaticallyincreasesgate
drivecurrentwhentheforwardinputvoltageexceeds25mV.
The LTC4416 “fast off” feature is engaged when the sense
voltageexceedstheinputvoltageby25mV.TheLTC4416-1
enables the fast off under the same conditions and when
the other external P-channel device is selected using the
enablepins.
