Power Good Operation
Local power is measured by several circuits shared with the overtemperature
system. The Pwr_LED_Drive Output is indirectly controlled by the on-board
microcontroller. The on-board PWM switching controller measures +3.3V and
+5V output voltages and all output currents. The microcontroller measures
input voltage and the +12V output voltage. The system requires that the input
voltage is within normal tolerances at all times. If the input voltage is too
high very briefly at startup (but not exceeding the absolute input voltage), the
system will start normally if the input voltage reaches acceptable limits quickly
(under half a second). This typically occurs as a load is applied.
briefly until all on-board startup conditions are met (less than half a second) at
which point the LED is illuminated. The operation proceeds as follows:
and/or the output current is excessive, the outputs are all shut down and the
Pwr_LED_Drive Output is desasserted (LO, lamp dark). The system will attempt
to restart in about half a second by briefly turning on all outputs. If successful and
the fault is eliminated, the Pwr_LED_Drive Output will be asserted (HI, lamp lit)
and operation continues.
