guidelines of 48V, 200W boards. Its 6A circuit breaker current
rating allows the QPI-8 to provide 200W of power down to
the minimum bus voltage of 36V. Its 12A maximum current
limit allows for fast charging of a converters input bulk
storage capacitance. Its ability to retry after a circuit
breaker fault time-out enables the QPI-8 to charge large
amounts of bulk capacitance through multiple 12A current
pulses before signaling that power is good via the PWRGD
pin. This signal should be used to enable the QPI-8s load
converter.
 
 
Figure 11 - 2 second short applied across QPI-8's outputs. 
 
The waveforms shown in Figure 11 are of a running QPI-8
that has a short applied across its output for a 2 second
duration. The PWRGD signal (blue, CH1) is initially high, the
VSW voltage (light blue, CH2) is low with respect to BUS-, and 
the input current (green, CH4) is at a minimum load.
 
With a short applied, PWRGD drops to a low value and the
voltage on VSW returns to the BUS+ value. The QPI-8 detects
a current fault and begins a cycle of trying to charge the bulk
capacitors, then waiting. Once the short is lifted, the QPI-8
charges the bulk capacitor by the third pulse of current, also
signaling that power is once again good. During the short
circuit the input current is limited to 12A peaks, with an on
duty cycle of about 1%.
 
The QPI-8 has a default under-voltage limit of 34V to turn on,
and 32V to turn off. The over-voltage limit is 76V to turn off,
72V to turn on. The high-side of each resistor string is
brought out to allow the user to trim up one or both of the
voltage limits, or the pins can be connected directly to BUS+
for the default under and over voltage limits. The equations
in Figure 12 provide the new trip point voltages for a given
added series resistor, R

Having access to the high side of the internal resistor divider
string enables the user to filter one or both nodes, allowing

The normal response of the QPI-8 to a BUS supply transient
which drops below the UV limit is to assert the PWRGD pin
low and shut off its pass FET. When the UV requirements are
