Data Sheet: AscetaTM iQL Series –Single Output Quarter Brick
Operating Information:
Over-Current Protection: The power
modules have current limit protection to
protect the module during output overload
and short circuit conditions. During overload
conditions, the power modules may protect
themselves by entering a hiccup current limit
mode. The modules will operate normally
once the output current returns to the
specified operating range. A latched over-
current protection option is also available.
Consult the TDK Innoveta technical support
for details.
Output Over-Voltage Protection: The
power modules have a control circuit,
independent of the main control loop, that
reduces the risk of over voltage appearing at
the output of the power module during a
fault condition. If there is a fault in the main
regulation loop, the over voltage protection
circuitry will latch the power module off once
it detects the output voltage condition as
specified on the Electrical Data page. To
remove the module from the latched
condition, either cycle the input power or
toggle the remote ON/OFF pin providing that
over-voltage conditions have been removed.
The reset time of the ON/OFF pin should be
500ms or longer.
An optional non-latching OVP protection
feature is also available. Consult the TDK
Innoveta technical support for details.
Thermal Protection: When the power
modules exceed the maximum operating
temperature, the modules will turn-off to
safeguard the units against thermal damage.
The module will auto restart as the unit is
cooled below the over temperature
threshold. A latched over-temperature
protection option is also available. Consult
the TDK Innoveta technical support for
details.
Remote On/Off: - The power modules have
an internal remote on/off circuit. The user
must supply an open-collector or compatible
switch between the Vin(-) pin and the on/off
pin. The maximum voltage generated by
the power module at the on/off terminal is
15V. The maximum allowable leakage
current of the switch is 50uA. The switch
must be capable of maintaining a low signal
Von/off < 0.8V while sinking 400uA.
The standard on/off logic is negative logic.
The module will turn on if pin 2 is connected
to pin 3, and it will be off if pin 2 is left open.
If the negative logic feature is not being
used, pin 2 should be shorted to pin 3.
An optional positive logic is available. The
power module will turn on if pin 2 is left open
and will be off if pin 2 is connected to pin 3.
If the positive logic circuit is not being used,
terminal 2 should be left open.
