Power-Out Connectors
M1 System Management Board User’s Guide
Note:
The output voltage of the FETs goes to two different power-out connectors:
ATX Connector J73 – Any external daughter board can be plugged into this connector. All voltages on the J73
connector are monitored by the M1AFS1500-FG484 device.
MB_PS_ON# – This signal may be driven by an external daughter board. It is an output from the external daughter
board. The function of the signal is similar to the PS_ON signal. This signal behaves as a switch to the power going to
the external daughter board.
MB_POWER_OK – This sense/flag signal is an input to the external daughter board. It indicates whether the power
going to the external board is good. This signal is driven by the M1AFS1500-FG484 device.
Header pins – Header pins are provided for 12 V, 5 V, and 3.3 V in the current monitored external daughter board
section of the board. Alligator clips can be used to connect any external board to these pins to power the board. All
voltages and current are monitored using 0.1 Ω resistors through the M1AFS1500-FG484 device.
Note:
The gate driver has to be configured as a constant current sink with a 10-μa or 30-μa drive level to get different
ramp-rates.
The external board connected to the header pins consumes less than 3 A.
