GENERAL DESCRIPTION
The evaluation system is composed of a motherboard and
a daughterboard. The motherboard provides the I
from the computer USB port and generates the I/O voltages
and digital high and low signals for the daughterboard. For
temperature measurement, the daughterboard can be either

The motherboard features a 3.3 V regulator and a 1.8 V
regulator. The jumpers on the bottom left of the motherboard
set the VIC voltage, which is the I
Users can choose among the 1.8 V, 3.3 V, or 5 V USB or the
external VBAT as the supply voltage for the daughterboard.
The daughterboard contains numerous jumpers and test points
for easy evaluation of the board. Also included with the kit are
two current probes that can be plugged directly into jumper
heads to measure currents with current probes.
Warning
For safety reasons, do not look directly into the LEDs at close
range. They are very bright and can cause eye injury.

EVAL-ADP1653EB FAQS Why does the solution size seem bigger than was expected? Why is the logic level of INTF equal to VBAT/2, whereas all others are 1.8 V? This board (4.0.1) is intended as an evaluation board, with easy access to test points and current measurements and the ability It is not envisaged that customers will change between HW and I to switch components easily. -
