LFCSP Demo Board Typical Operation Setup
TYPICAL OPERATION
The typical test setup for the
charger consists of a dc
power supply unit (PSU) for VIN_F, a source meter unit (SMU)
or a battery simulator for the ISO_Bx pins, and a variable power
resistor or electronic load for the ISO_Sx pins.
The SMU at the ISO_B_F node must have a 100 mΩ to 250 mΩ
resistor (R
S
) in series with its positive lead. The resistor emulates
the equivalent series resistance of a real battery. Some SMU
models that have been successfully used for the ISO_x_F node
include the following:
•
Keithley 2306 battery simulator
•
Keithley 2602A SMU
•
Agilent 6784A/6762A SMU
