APPLICATIONS INFORMATION
MOSFET Configurations and Selection
The LTC4360 can be used with various external MOSFET
configurations(seeFigure3).Thesimplestconfigurationis
a single N-channel MOSFET. It has the lowest RDS(ON) and
voltage drop and is thus the most power efficient solution.
When GATE is pulled to ground, the MOSFET can isolate
OUT from a positive voltage at IN up to the BVDSS of the
MOSFET. However, reverse current can still flow from OUT
to IN via the parasitic body diode of the MOSFET.
FornearzeroreverseleakagecurrentprotectionwhenGATE
is pulled to ground, back-to-back N-channel MOSFETs can
beused.AddinganadditionalP-channelMOSFETcontrolled
by GATEP (LTC4360-2) provides negative input voltage
protection down to the BVDSS of the P-channel MOSFET.
Another configuration consists of a P-channel MOSFET
controlled by GATEP and a N-channel MOSFET controlled
byGATE.Thisprovidesprotectionagainstovervoltageand
negative voltage but not reverse current.
Input Transients
Figure 4 shows a typical set-up when an AC wall adaptor
charges a mobile device. The inductor LIN represents the
lumpedequivalentinductanceofthecableandtheEMIfilter
found in some wall adaptors. RIN is the lumped equivalent
resistance of the cable, adaptor output capacitor ESR and
the connector contact resistance.
