EVALUATION BOARD OVERVIEW
USB A
TYPICAL OPERATION
The typical test setup for the
power supply unit (PSU) for VIN_F, a source meter unit (SMU)
or a battery simulator for the ISO_B_x pins, and a variable power
resistor or electronic load for the ISO_S_x pins.
When the charger operates at high current rates, the voltage drop
over the USB cable and USB connectors can be significant. For
easy evaluation of real cable and connector losses, the
evaluation kit contains an USB cable and an USB A adapter board
that includes a screw terminal for the VIN_F voltage supply.

WLCSP Demo Board Typical Operation Setup.
The SMU at the ISO_B node must have a 100 mΩ to 250 mΩ
resistor (R
) in series with its positive lead. The resistor emulates
S
the equivalent series resistance of a real battery. Some SMU
models that have been successfully used for the ISO_Bx node
include the following:
•
Keithley 2306 battery simulator
•
Keithley 2602A SMU
•
Agilent 6784A/6762A SMU
