Note:
The following headers must be populated with one jumper for the UCS81003
Evaluation Board to be functional:
• J4, J5, J8
• J16 or J18
• J17 or J19
• If
UCS81003 is configured in SMBus mode (as selected by using J16 instead of J18), two
jumpers must be populated on J7 and J6 must be left unpopulated.
If
UCS81003 is
configured in Stand-Alone mode, the jumpers on J7 must be left off.
2.5 DATA TEST POINTS ON THE EVALUATION BOARD
Figure 2-4 shows the top of the board and highlights the USB data line test points.
FIGURE 2-4: Evaluation Board Top View – Data Test Points.
J19 SMBus Address
PWR_EN active high
Placing one jumper on this header selects the SMBus
address and sets the PWR_EN control to be active high. In
this case, no jumper must be populated on J17 header.
