FEATURES DESCRIPTIONS
Over-Current Protection
The modules include an internal output over-current
protection circuit, which will endure current limiting for
an unlimited duration during output overload. If the
output current exceeds the OCP set point, the modules
will automatically shut down, and enter hiccup mode or
latch mode, which is optional.
For hiccup mode, the module will try to restart after
shutdown. If the overload condition still exists, the
module will shut down again. This restart trial will
continue until the overload condition is corrected.
For latch mode, the module will latch off once it
shutdown. The latch is reset by either cycling the input
power or by toggling the on/off signal for one second.
Over-Voltage Protection
The modules include an internal output over-voltage
protection circuit, which monitors the voltage on the
output terminals. If this voltage exceeds the over-voltage
set point, the module will shut down, and enter in hiccup
mode or latch mode, which is optional.
For hiccup mode, the module will try to restart after
shutdown. If the output overvoltage condition still exists,
the module will shut down again. This restart trial will
continue until the over-voltage condition is corrected.
For latch mode, the module will latch off once it
shutdown. The latch is reset by either cycling the input
power or by toggling the on/off signal for one second.
Over-Temperature Protection
The over-temperature protection consists of circuitry
that provides protection from thermal damage. If the
temperature exceeds the over-temperature threshold
the module will shut down, and enter in auto-restart
mode or latch mode, which is optional.
For auto-restart mode, the module will monitor the
module
temperature
after
shutdown.
Once
the
temperature is dropped and within the specification, the
module will be auto-restart.
For latch mode, the module will latch off once it
shutdown. The latch is reset by either cycling the input
power or by toggling the on/off signal for one second.
Remote On/Off
The remote on/off feature on the module can be either
negative or positive logic. Negative logic turns the module
on during a logic low and off during a logic high. Positive
logic turns the modules on during a logic high and off
during a logic low.
Remote on/off can be controlled by an external switch
between the on/off terminal and the Vi(-) terminal. The
switch can be an open collector or open drain.
For negative logic if the remote on/off feature is not used,
please short the on/off pin to Vi(-). For positive logic if the
remote on/off feature is not used, please leave the on/off
pin floating.
