Highly Integrated Single-Cell Li-ion/Li-Polymer
Battery Charger
Application Note
May 5, 2009
AN1049.1
Introduction
The ISL6291 is a highly integrated single-cell
Li-ion/Li-polymer battery charger designed for handheld
devices. The ISL6291EVAL1 provides a convenient platform
to evaluate the integrated charger. This application note first
describes the components on this board so a user can
perform their own evaluation. Then it presents the
evaluations that can be carried out with this board. At the
end of this application note are the schematics, the layout of
each layer, and the bill-of-materials.
The other end of the thermistor is expected to be connected
to the ground of the battery pack.
DIP Switch
A 9-bit DIP switch is located on the bottom edge of the
board. This DIP switch allows users to set up various
TIMEOUT lengths, charger current levels, end-of-charge
current, and to simulate battery removal, and so on. The
function of each bit is summarized in Table 1.

given at the end of this application note.
JP1
JP1 is a two-pin connector for the input power located on the
left edge of the evaluation board. Connect the pin labeled
with “+” to the positive output of the power source and the
pin labeled with “GND” to the ground output of the power
source. The input voltage is expected to be between 4.3V to

10V, and the current up to 2A.
JP2
JP2 is a three-pin connector located on the right edge. JP2
interfaces the charger output to a Li-ion battery pack. The
pins labeled with “+” and “GND” should be connected to the
positive and ground terminals of the battery pack
respectively. The pin labeled with “TEMP” should be
connected to the NTC thermistor output of the battery pack.
Jumpers
Three 2-pin jumpers are used in this evaluation board. JP3
connects the input power source to the VIN pin of the
charger IC when it is shorted. JP4 connects the charger
output to connector JP2. These two jumpers are employed
for the convenience of input and output current
measurement. A current meter can be inserted when the
jumper is opened. Opening the third jumper, JP5,
disconnects the TEMP pin to the thermistor of the battery
pack. When JP5 is disconnected, the DIP switch can be
used to simulate high temperature, low temperature, and
battery removal cases. Refer to the schematic for more
information.
Test Points
Five test points are available on the board for the
convenience of evaluation. GND1 and GND2 are two ground
connection points. The VIN, the VBAT, and the TIME test
point connects to the charger IC pins of the same name.
