Output Undervoltage
The output voltages on all supplies, except the -12V
supply, are monitored for undervoltage. Output under-
voltage fault management is identical to the output
overcurrent fault management. Figures 5, 6, and 7 can
be used to illustrate undervoltage faults on the
MAX5915/MAX5915A/MAX5916/MAX5916A.
Thermal Shutdown Control
The MAX5915/MAX5915A/MAX5916/MAX5916A feature
internal thermal protection. Two thresholds detect when
the device is overheated. If the first threshold is reached,
the channel that is in overcurrent shuts down. If the sec-
ond thermal threshold is reached, the entire device shuts
down. The device cannot be restarted until the thermal
condition is cleared. For the MAX5915, the main chan-
nels turn back on after +12VIN or ON_ is toggled. For the
MAX5916, the main channels turn back on after
t
RESTART
. The auxiliary channels for the MAX5915/
MAX5915A/MAX5916/MAX5916A restart after t
RESTART
.
PGOOD_ Operation
The MAX5915/MAX5915A/MAX5916/MAX5916A incor-
porate a PGOOD_ output to report when power is good
to a microprocessor or controller. PGOOD_ remains low
if the auxiliary outputs are not powered, for PCI and
compact PCI systems where the 3.3VAUX is not avail-
able. Connect 3.3VAUXIN to 3.3VIN and connect
AUXON_ to ON_ to allow PGOOD_ to transition high
when the main supplies are available. The open-drain
structure of PGOOD_ requires an external pullup resis-
tor (see the Functional Diagram). Figure 8 shows the
internal logic of the PGOOD_ output.
