Symbol Description of the Connections
J3 This is the USB Type B connector to connect to the computer.
J4 This allows the user to either: (1) connect jumpers horizontally to the top and bottom pin
pairs to connect to the on-board MMBT3904 or (2) to remove the jumpers and connect a
remote diode directly to the input of the LMxx.
JP2 TCRIT# and ALERT# are the open drain LMxx output pins VDC (+3.3 VDC), and the
SMBus Clock and Data signals are available to the user for system monitoring.
