DESCRIPTION
Dual 2.6A, 2.5V to 5.5V
Fast Ideal Diodes
in 3mm × 3mm DFN
The LT C
®
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
diodes use a 100mΩ P-channel MOSFET to independently
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
fault conditions. An internal overvoltage protection sensor
detects when a voltage exceeds the LTC4413-2 absolute
maximum voltage tolerance.
Two active-high control pins independently turn off the two
ideal diodes contained within the LTC4413-1/LTC4413-2.
When the selected channel is reverse biased, or the
LTC4413-1/LTC4413-2 is put into low power standby, the
status signal is pulled low by an 11µA open drain.
The LTC4413-1/LTC4413-2 are housed in a 10-lead 3mm
× 3mm DFN package.
