ISL9208EVAL1Z
Rev D Evaluation Board
Description
This document is intended for use by individuals engaged in
the development of hardware for a 4 to 7 series connected Li-
ion battery pack using the ISL9208EVAL1Z (Rev D) board.
The evaluation kit consists of the ISL9208EVAL1Z (Rev D)
board, a power supply cable and an I
the ISL9208EVAL1Z (Rev D) board requires the use of a USB
2
to I C kit and part number "ISLI2C-Cable2", which is ordered
separately. An optional link between the PC and the
microcontroller BKGD connector is available from NXP
(formerly Freescale) for monitoring and debugging the
microcontroller code.
First Steps
• If not already available, acquire the DeVaSys USB to I
interface cable and module. This is available from Intersil
in the ISLI2C-Cable kit.
• Download the software from the Intersil website on the
ISL9208 page. This is a zip file entitled: "ISL92xx Eval Kit
Software Release V1.41".
• Unzip the software files to a directory of your choice.
• Prior to powering the ISL9208 board, install the USB to I
board software and connect the DeVaSys board to the PC
(see Appendix 1). However, don't connect the DeVaSys
board to the ISL9208EVAL1Z (Rev D) board, yet. This is
just preparation of the test set up. With these pieces in
place, the PC interface can then quickly be used to monitor
the operation of the board, once power is applied.
• If changes to the microcontroller code are desired, then it will
be necessary to order a programming/debug module from
NXP (formerly Freescale), part number,
USBMULTILINKBDME. This kit also contains the Code

• Set-up a power supply for the board. The power supply
should consist of a string of 4 to 7 batteries (see Figure 1),
or a string of 4 to 7 resistors and a power supply, or 4 to 7
individual power supplies (see Figure 1 or Figure 2).
Battery/Power Supply Connection
When connecting battery packs or power supplies, use the
connections of Figure 1 and Figure 2. If individual power
supplies are being used to replace battery cells, then
connect the power supplies identically to the battery
connections (see Figure 1). Also, make sure that the
individual power supply voltages do not exceed the ISL9208
maximum input voltage differential of 5V per cell.
If using a string of resistors to emulate the battery cells, then
use the connection in Figure 2. In this case, limit the power
supply voltage so that the resistor divider outputs do not
exceed the ISL9208 input maximum ratings.
It is recommended that, when using the circuit of Figure 2, the
series resistors be 20 or less and 2W minimum. Resistors
C
with higher resistance can be used, but when activating the
ISL9208 cell balance outputs, the 39 cell balance resistor on
the board will lower the voltage across that series power
supply resistor while raising the voltage on all of the other
series resistors. Turning on multiple cell balance outputs could
then result in one or more of the VCELLN input voltages
exceeding their maximum specified limit. If using series
resistors greater than 20, the cell balance resistors on the
ISL9208EVAL1Z (Rev D) board (R
replaced with higher values (1k recommended).
