LTC4358
5A Ideal Diode
FEATURES DESCRIPTION n The LTCВ®4358 is a 5A ideal diode that uses an internal
20mО© N-channel MOSFET to replace a Schottky diode
when used in diode-OR and high current diode applications. The LTC4358 reduces power consumption, heat
dissipation, and PC board area. Replaces a Power Schottky Diode
Internal 20mО© N-Channel MOSFET
0.5Ојs Turn-Off Time Limits Peak Fault Current
Operating Voltage Range: 9V to 26.5V
Smooth Switchover without Oscillation
No Reverse DC Current
Available in 14-Pin (4mm Г— 3mm) DFN and
16-Lead TSSOP Packages The LTC4358 easily ORs power supplies together to increase total system reliability. In diode-OR applications,
the LTC4358 regulates the forward voltage drop across
the internal MOSFET to ensure smooth current transfer
from one path to the other without oscillation. If the power
source fails or is shorted, a fast turnoff minimizes reverse
current transients. APPLICATIONS N+1 Redundant Power Supplies
