DescripTion
Dual 2.6A, 2.5V to 5.5V,
Ideal Diodes in 3mm
×
3mm DFN
The LT C
®
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
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 fault conditions.
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.
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
selected diode is conducting with a high voltage. This signal
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.
The LTC4413 is housed in a 10-lead DFN package.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: The LTC4413 is guaranteed to meet performance specifications
from 0°C to 85°C. Specifications over the –40°C to 85°C operating
temperature range are assured by design, characterization and correlation
with statistical process controls.
Note 3: Quiescent current increases with diode current, refer to plot of I
QF
vs I
OUT
.
Note 4: This IC includes overtemperature protection that is intended
to protect the device during momentary overload conditions.
Overtemperature protection will become active at a junction temperature
greater than the maximum operating temperature. Continuous operation
above the specified maximum operating junction temperature may impair
device reliability.
Note 5: This specification is guaranteed by correlation to wafer-level
measurements.
Note 6: Unless otherwise specified, current into a pin is positive and
current out of a pin is negative. All voltages referenced to GND.
Note 7: Guaranteed by design.
