LTC4359

Ideal Diode Controller with

Reverse Input Protection

FeaTures

DescripTion

TheLTC^®4359isapositivehighvoltageidealdiodecontrol-

ler that drives an external N-channel MOSFET to replace

a Schottky diode. It controls the forward voltage drop

across the MOSFET to ensure smooth current delivery

without oscillation even at light loads. If a power source

fails or is shorted, a fast turn-off minimizes reverse cur-

rent transients. A shutdown mode is available to reduce

the quiescent current to 9μA.

Reduces Power Dissipation by Replacing a Power

Schottky Diode

Wide Operating Voltage Range: 4V to 80V

Reverse Input Protection to –40V

Low 9µA Shutdown current

Low 150μA Operating Current

Smooth Switchover without Oscillation

Available in 6-Lead (2mm × 3mm) DFN and 8-Lead

MSOP Packages

Whenusedinhighcurrentdiodeapplications,theLTC4359

reducespowerconsumption,heatdissipation,voltageloss

and PC board area. With its wide operating voltage range,

the ability to withstand reverse input voltage, and high

temperature rating, the LTC4359 satisfies the demanding

requirementsofbothautomotiveandtelecomapplications.

The LTC4359 also easily ORs power sources in systems

with redundant supplies.
