GENERAL DESCRIPTION

The
ADP5062
charger evaluation system is composed of an
evaluation board, an USB A to USB micro B cable and an USB
A adapter board. All evaluation board functions and circuits are
2
controlled via one I
C bus connector. The I
with the
ADP5062
directly, and the digital input/output signals
are controlled through an on-board input/output expander
2
circuit on the I
C bus. The evaluation board also features a 3.4
V regulator for VDDIO generation. The board contains jumpers
and numerous test points for easy evaluation.
The ADP5062CP-EVALZ evaluation kit contains a CD with the
ADP5062 GUI 3v0 installer. Use the GUI in conjunction with
the USB-SDP-CABLEZ, USB to Serial I/O Interface.
Full performance details are provided in the
sheet, and the
ADP5062
data sheet should be consulted in
conjunction with this user guide.
