LTC4413-1/LTC4413-2

Dual 2.6A, 2.5V to 5.5V

Fast Ideal Diodes

in 3mm × 3mm DFN

FEATURES

DESCRIPTION

The LTC^®4413-1 and LTC4413-2 each contain two mono-

lithic ideal diodes, each capable of supplying up to 2.6A

from input voltages between 2.5V and 5.5V. The ideal

diodesusea100mΩP-channelMOSFETtoindependently

connect INA to OUTA and INB to OUTB. During normal

forward operation, the voltage drops across each of

these diodes are regulated to as low as 18mV. Quiescent

current is less than 80μA for diode currents up to 1A. If

either of the output voltages exceeds its respective input

voltage, that MOSFET is turned off and less than 1μA of

reverse current ﬂows from OUT to IN. Maximum forward

current in each MOSFET is limited to a constant 2.6A and

internal thermal limiting circuits protect the part during

faultconditions.Aninternalovervoltageprotectionsensor

detects when a voltage exceeds the LTC4413-2 absolute

maximum voltage tolerance.
