DESCRIPTION
Positive High Voltage
Ideal Diode-OR with Input Supply
and Fuse Monitors
The LTC4355 is a positive voltage ideal diode-OR control-
ler 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.
With the LTC4355, power sources can easily be ORed
together to increase total system reliability. The LTC4355
can diode-OR two positive supplies or the return paths of
two negative supplies, such as in a –48V system.
In the forward direction the LTC4355 controls the volt-
age drop across the MOSFET to ensure smooth current
transfer from one path to the other without oscillation. If
a power source fails or is shorted, fast turnoff minimizes
reverse current transients.
Power fault detection indicates if the input supplies are
not in regulation, the inline fuses are blown, or the volt-
ages across the MOSFETs are greater than the fault
threshold.
