Application Diagram (continued)
The TPS2363 has bleed-down circuits to discharge the module before it is removed, when the voltages are
below the low comparator threshold, slot PWROFF will be set indicating it is safe to remove the module. This is
available over the SMBus.
Gate capacitors are used to set the rise time, this allows soft turn on of the slot avoiding power glitches.
The TPS2363 can be operated in direct mode, which does not use the SMBus.
The TPS2363PFB without the A/D converter in a 48-pin package is a drop in replacement for the competitive
parts but with certain improvements.
Improvements Over the Competition
The function register is exclusive to the TPS2363 to provide additional functionality.
VAUXA/B programmable to higher current, the ability to step the current to 800 mA. Several add-in modules
in the past have not been able to stay under the allowed current in the PCI standards.
AUX current limit is more accurate; TPS2363 400 mA to 750 mA vs MIC2592B 375 mA to 1.35 A.
2 Inputs for slot with debounce, each slot normally has a switch and attention button.
The ability to turn off current limit with the SMBus, some applications prefer the circuit breaker and do not
want current limit.
VAUX independent of main power.
Power off slot information with the SMBus, this shows that all the voltages on the module are below 100 mV
and the module can be removed safely.
Tighter fault timer control.
AUXENA/B is level sensitive, not edge triggered.
