Performance Waveforms
Start-up
The following oscilloscope pictures show the Hot-Swap
BUS- current, QPI- to Bus- voltage and PWRGD (Powergood)
to BUS- output voltage of the QPI-8 during operation.
Figures 10 and 11
are the QPI-8’s in-rush characteristics
under two load capacitance conditions.
In
Figure 10
a 470 μF capacitor required roughly 170 ms to
completely charge from a 48 V bus voltage. The QPI-8 can
drive large amounts of bulk capacitance, as shown in
Figure 11
with a 4700 μF load capacitance. Under this
condition the PWRGD signal takes about 8.7 seconds to go
high after the UVEN input is pulled high upon the
completed insertion of the board into the shelf.
Figure 11’s
time-scale is too long to show the current pulses that
charge the bulk capacitance.
After insertion, when the UVEN voltage exceeds 34 V the
UV detection fault is cleared, the QPI-8 goes through a
delay cycle (~15 ms) to allow for system de-bounce and
stabilization. After this time, the QPI- to BUS- path is
turned on and current is allowed to pass, monitored by
the current sense function. Initially the current level
exceeds the 6 A circuit breaker limit, the event timer starts
and the Powergood state is not valid. The sense function
and linear control loop will allow twice the circuit breaker
current to pass. If the current does not drop below the
circuit breaker level prior to reaching the timer limit,
typically 275 μs, the QPI- to BUS- path will open. The
effective duty cycle under the current limit condition is
approximately 1%. Once the load capacitors are fully
charged to the input bus potential, the load condition
falls below 6 A and the PWRGD pin is asserted high,
providing that the bus supply is still within the UV and
OV range.
Transient Protection and Recovery
Figures 12 and 13
show the QPI-8’s ability to handle low
resistance shorts (<2
) at the load terminals to emulate
fast and slow blown fuse events. In
Figure 12
, the
transient short is 2 seconds long and the QPI- to BUS- path
is opened within 400 μs of this occurrence.
Figure 13
demonstrates the QPI-8’s performance with a
short circuit on its output. The QPI-8 remains in a low duty
cycle mode until the short is removed, then restarts normally.
