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 ISL9208EVAL2Z board.

The evaluation kit consists of the ISL9208EVAL2Z board.

Operation of the ISL9208EVAL2Z board requires the use of

a USB to I

separately. An optional link between the PC and the

microcontroller BKGD connector is available from Freescale

(used for monitoring and debugging the microcontroller

code).

First Steps

• If not already available, acquire the DeVaSys USB to I

• Download the software from the Intersil website on the

connect the DeVaSys board to the ISL9208EVAL2Z 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.

Battery/Power Supply Connection

When connecting battery packs or power supplies, use the

connections of Figures 1 and 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 20Ω or less and 2W minimum.

Resistors with higher resistance can be used, but when

activating the ISL9208 cell balance outputs, the 39Ω 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 20Ω, the cell

balance resistors on the ISL9208EVAL2Z board (R14-R20)

should be replaced with higher values (1kΩ recommended).
