GLOBAL POWER GOOD
Signal
The
GLOBAL POWER GOOD
signal is an unbiased open collector signal that is
available on the J1005 system signal connector via the collector on pin 5 and the
emitter on pin 1 (common). This signal is activated when all modules report
individual
POWER GOOD
signals for their outputs. There is a 390 Ω resistor in
series with the collector for current limiting. When all modules have an output within
10% of V
set
, the transistor turns on. The transistor turns off when the output of any
module is outside 10% of V
set
.

Global Enable/Inhibit (Control)
You can enable or inhibit all module outputs simultaneously by using the control pin
input on the J1005 system signal connector, between pin 3 (control) and pin 1
(common). Under normal conditions, pin 3 is pulled to 5 V internally (logic high) and
all modules are enabled. To disable all modules, pull pin 3 to common (logic low).
There is up to a 20 ms delay from change in signal logic to change in output voltage.
The input has a 1 kΩ series resistor and a 100 nF filtering capacitor to filter noise on
this signal. The maximum allowable voltage on pin 3 is 5 V.
Overtemperature Protection
The CoolX unit monitors internal temperatures on the power supply to ensure that
component temperatures do not exceed their ratings. The
OVERTEMPERATURE
PROTECTION
(OTP) warning signal is an unbiased open collector signal that is
available on the J1005 system signal connector via the collector on pin 7 and the
emitter on pin 1 (common). There is a 390 Ω resistor in series with the collector for
current limiting.
During normal operation, the transistor is turned off. If an overtemperature condition
is detected, the
OVERTEMPERATURE PROTECTION
signal will be pulled low via
the 390 Ω resistor as a warning of a possible shutdown of the power supply. If the
