HV301/HV311
Redundant Supplies
Many systems use redundant primary power supplies or battery
backup. When redundant AC powered sources are used they are
generally diode OR’ed to the load on the hot terminal.
For these systems, the use of independent hotswap controllers
is recommended with the diode OR’ing provided after the hotswap
Application Information, cont’d.
controllers. The HV311 is ideally suited for such applications
since two or more active low PWRGD signals can be connected
to a single active low ENABLE pin, thus enabling the load as long
as at least one primary power source is available. By adding low
current 100V diodes in series with the V
pins, full reverse
polarity protection on either power source is also provided
(
