Using the ISL612XSEQEVAL1 Platform
The
ISL612XSEQEVAL1
platform is the primary evaluation
board for this family. The board has 2 complete, separate
and electrically identical circuits, see Figure 15 for schematic
and Figure 16 for a photo.
In the top right hand corner of the board is a SMD layout with
a
ISL6123
illustrating the full functionality and small
implementation size for an application having the highest
component count.
The majority of the board is given over to a socket and
discrete through-hole components circuit for ease of
evaluation flexibility through IC variant swapping and
modification of UVLO levels and sequencing order by
passive component substitution.
The board is shipped with the
ISL6123
installed in both
locations and with two each of the other released variant
types loose packed. As this sequencer family has a common
function pinout there are no major modifications to the board
necessary to evaluate the other ICs. The
ISL6125
due to its
having open drain outputs can be evaluated on the
ISL612XSEQEVAL1
with a minor modification or on the
ISL613XSUPEREVAL2
evaluation platform. To modify for
ISL6125
evaluation, pull-up resistors must be added from
the GATE outputs to a pull-up voltage of 1.5V to prevent FET
turn-on or remove FETs to eliminate this voltage restriction.
To the left, right and above the socket are four test point
strips (TP1-TP4). These give access to the labeled IC I/O
pins during evaluation. Remember that significant current or
capacitive loading of particular I/O pins will affect
functionality and performance.
Attention to orientation and placement of variant ICs in the
socket must be paid to prevent IC damage or faulty
evaluation.
The default configuration of the
ISL612XSEQEVAL1
circuitries was built around the following design
assumptions:
