J11
No jumper = voltage input to
power switch coming from auxiliary
power input (J3)
Jumper = voltage input to power
switch coming from host (J2)
J12
SMBus
Applicable only to UCS1002. Jumpered pins select the corresponding
resistor which selects the ILIM setting.
J13
STAND ALONE
Applicable only to UCS1001 and UCS1002 in stand-alone mode. Jumpered
pins select the corresponding resistor which selects the ILIM setting.
J14
ACTIVE LOW
No jumper selected, see J17
Install 1 jumper (J14-J17) to select an
SMBus address.
J15
J15
Jumper = voltage output from
power switch going to the portable
device (P1)
No jumper = voltage output from
power switch going to auxiliary power
output (J16)
J16
SDA_8051
Jumpered = SMBus via 8051
No jumper = external SMBus host
J17
ACTIVE HIGH
Jumper = 15-16 installed =
address 57h
Install 1 jumper (J14-J17) to select an
SMBus address.
J18
SCL_8051
Jumpered = SMBus via 8051
No jumper = external SMBus host
