FeaTures

DescripTion

The LTC^®4413 contains two monolithic ideal diodes,

each capable of supplying up to 2.6A from input voltages

between 2.5V and 5.5V. Each ideal diode uses a 100mΩ

P-channel MOSFET that independently connects INA to

OUTA and INB to OUTB. During normal forward operation

the voltage drop across each of these diodes is regulated

to as low as 28mV. Quiescent current is less than 40µA

for diode currents up to 1A. If either of the output voltages

exceeds its respective input voltages, that MOSFET is

turned off and less than 1µA of reverse current will ﬂow

fromOUTtoIN.MaximumforwardcurrentineachMOSFET

is limited to a constant 2.6A and internal thermal limiting

circuits protect the part during fault conditions.

Package

Two active-high control pins independently turn off the

two ideal diodes contained within the LTC4413, control-

ling the operation mode as described by Table 1. When

the selected channel is reverse biased, or the LTC4413 is

put into low power standby, a status signal indicates this

condition with a low voltage.

Battery and Wall Adapter Diode ORing in Handheld

A 9µA open-drain STAT pin is used to indicate conduction

status. When terminated to a positive supply through a

470k resistor, the STAT pin can be used to indicate that the

selecteddiodeisconductingwithahighvoltage.Thissignal

can also be used to drive an auxiliary P-channel MOSFET

power switch to control a third alternate power source

when the LTC4413 is not conducting forward current.
