Table 3: Signal Definitions
All hardware alarm signals (Fault, PFW, OTW, Power Capacity) are open drain FETs. These signals need to be pulled HI to either 3.3V or 5V.
Maximum sink current 5mA. An active LO signal (< 0.4V
DC
) state. All signals are referenced to Logic_GRD unless otherwise stated.
Function Label Type Description
Output Enable Enable Input If shorted to Logic_GRD main output is ON in Analog or PMBus mode.
Power Fail Warning PFW Output An open drain FET; Changes to LO  5msec before the output decays below 40V
DC
.
I 2 C Interrupt Alert#_0/Alert#_1 Output This signal is pulled to 3.3V via a 10kΩ resistor. Active LO.
Rectifier Fault Fault Output An open drain FET; normally HI, changes to LO.
Module Present MOD_PRES Output Short pin, see Status and Control description for further information on this signal.
ON/OFF ON/OFF Input Short pin, controls main output during hot-insertion and extraction. Ref: Vout ( - )
Protocol select Protocol Input Selects operational mode. Ref: Vout ( - ). No-connect PMBus, 10kΩ - RS485
Margining Margin Input Changes the default set point of the main output.
Over-Temperature Warning OTW Output Open drain FET; normally HI, changes to LO 5°C prior to thermal shutdown.
Power Capacity POWER_CAP Output Open drain FET; HI indicates 2725W operation and LO indicates 1200W operation.
Rectifier address Unit_addr Input Voltage level addressing of Rectifiers within a single shelf. Ref: Vout ( - ).
Shelf Address Shelf_addr Input Voltage level addressing of Rectifiers within multiple shelves. Ref: Vout ( - ).
Back bias 8V_INT Bi-direct Used to back bias the DSP from operating Rectifiers. Ref: Vout ( - ).
Mux Reset Reset Input Resets the internal PCA9541 multiplexer
Standby power 5VA Output 5V at 0.75A provided for external use
