Description
Positive High Voltage
Ideal Diode Controller
TheLTC4357isapositivehighvoltageidealdiodecontrol-
ler that drives an external N-channel MOSFET to replace a
Schottky diode. When used in diode-OR and high current
diodeapplications,theLTC4357reducespowerconsump-
tion, heat dissipation, voltage loss and PC board area.
The LTC4357 easily ORs power sources to increase total
system reliability. In diode-OR applications, the LTC4357
controls the forward voltage drop across the MOSFET to
ensure smooth current transfer from one path to the other
without oscillation. If the power source fails or is shorted,
a fast turn-off minimizes reverse current transients.
