DESCRIPTION
TheLTC®4359 isapositivehighvoltageidealdiodecontrol 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 current transients. A shutdown mode is available to reduce the quiescent current to 9μA.

FEATURES
■ 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

APPLICATIONS
■ Automotive Battery Protection
■ Redundant Power Supplies
■ Telecom Infrastructure
■ Computer Systems/Servers
■ Solar Systems
