LTC4355IS Datasheet PDF - Linear Technology

DESCRIPTION

●The LTC®4355 is a positive voltage ideal diode-OR controller that drives two external N-channel MOSFETs. Forming the diode-OR with N-channel MOSFETs instead of Schottky diodes reduces power consumption, heat dissipation and PC board area.

●FEATURES

●Replaces Power Schottky Diodes

●Controls N-Channel MOSFETs

●0.3μs Turn-Off Time Limits Peak Fault Current

●Wide Operating Voltage Range: 9V to 80V

●Smooth Switchover without Oscillation

●No Reverse DC Current

●Monitors VIN, Fuse, and MOSFET Diode

●Available in 14-Lead (4mm × 3mm) DFN, 16-Lead MS and SO Packages

●APPLICATIONS

●High Availability Systems

●AdvancedTCA® (ATCA) Systems

●+48V and –48V Distributed Power Systems

●Telecom Infrastructure
