SMSC EVB-UCS1002
PRELIMINARY - SMSC CONFIDENTIAL
J8 - M2
When installed, this jumper will force a low at the M2 pin.
J9 - SMCLK/S0
This jumper is applicable to the UCS1002 EVB only. It must be left off for SMBus communications
to be enabled.
If the UCS1002 is in stand-alone mode (as selected by using J13 instead of J12), detect power
state will be enabled without the jumper installed.
J10 - SMDATA/LATCH
For the UCS1002 with SMBus communications, this jumper must be left out.
For UCS1002 in stand-alone mode (as selected by using J13 instead of J12), this jumper will
enable the “auto-retry” fault handler if installed, and the “Latch” fault handler if left out.
J11 - VS Input Selection
This jumper connects the 5V pin of connector J2 to the UCS1001 or UCS1002 VS power input
pins. It MUST be left out if external power supply is connected to J3.
J12 - Current Limit
Current Limit (UCS1002 in SMBus mode only). This jumper selects the current limit. This is used
with the UCS1002 only.
J13 - Current Limit Stand-alone.
Current Limit. This jumper selects the current limit. This is used with the UCS1001 and the
UCS1002 when it’s in stand-alone mode.
J14 - Active Low Address
Active Low Address Selection. See datasheet for details. Only 1 jumper between J14 and J17 can
be selected at a time.
J15 - VBus Output
This jumper connects the 5V pin of connector P1 to the UCS1001 or UCS1002 VBUS power output
pins. It should be left off if power is to be drawn only from auxiliary power output connector P4.
J17 - Active High Address
Active High Address Selection. See datasheet for details. Only 1 jumper between J14 and J17 can
be selected at a time.
