2.3 Default Configuration Setup Options
The EVM has several default options for configuring for device and loadboard.
Table 3: ISL55180 Default Configuration Options
Mode
See Section # Brief Description
Hardware Reset
N/A
All registers default to the hardware default state.
Three-State (High-Z)
N/A
Puts DPS in three-state (high-Z). Opens all switches.
FV/MI 2.3.2
(default)
All Channels configured in FV/MI mode with I-Clamps disabled.
VFA = 3.0V, IR5, Sel-FB = SENSE, Con-FS = 1
Ch#0 FORCE and SENSE connected to TEST_NODE
Ch#0/1 Ganging
2.3.3
All Channels (except Ch#1) configured in FV/MI mode with
I-Clamps disabled. Ch#1 configured into FI-Slave mode
Ch#0 VFA = 3.0V, IR5, Sel-FB = SENSE, Con-FS = 1
Ch#0 FORCE and SENSE connected to TEST_NODE
Ch#1 FORCE connected to TEST_NODE
2.3.1 Remote Kelvin Sense
Caution should be used when configuring the feedback (SENSE) path to ensure the DPS does not
become open loop. The software defaults the CPU-Sel-FB = 2 (SENSE) and Con-FS# = 1 (closed) to
ensure the loop is closed. After connecting any external equipment to the FORCE/SENSE SMAs (or
TEST_NODE), the user can then set Con-FS#=0 (open) to provide remote Kelvin sensing.
