Output Overvoltage Protection
The output voltage is monitored at the V
pins of the module. If the voltage at these pins exceeds
the value indicated in the Feature Specifications table,
the module will shut down and latch off. Recovery from
latched shutdown is accomplished by cycling the dc
input power off for at least 1.0 second or toggling the
primary referenced on/off signal for at least 1.0 second.
Output Current Monitor
The CURRENT MON pin provides a dc voltage propor-
tional to the dc output current of the module given in
the Feature Specifications table. For example, on the
FW250A1, the V/A ratio is set at 65 mV/A
70 C case. At a full load current of 50 A, the voltage on
the CURRENT MON pin is 3.25 V. The current monitor
signal is referenced to the SENSE(–) pin on the sec-
ondary and is supplied from a source impedance of
approximately 2 k . It is recommended that the CUR-
RENT MON pin be left open when not in use, although
no damage will result if the CURRENT MON pin is
shorted to secondary ground. Directly driving the CUR-
RENT MON pin with an external source will detrimen-
tally affect operation of the module and should be
avoided.
