• Lead Free Status / RoHS Status: Lead free / RoHS Compliant

I
In some test conditions, ground connections can cause
problems. This is because the I
load, and perhaps an oscilloscope, may all connect to
ground. This can cause problems ranging from grounding
both sides of the power FETs (taking them out of the circuit)
to creating ground loops or unexpected voltage potentials
that can damage components.
The ISL9208EVAL2Z provides an option for the addition of
an isolation device for the I
ADuM1250. This allows the PC to monitor a battery pack
that is connected to a load without some of the grounding
problems that can arise. To use this option, the device and a
header needs to be installed on the board, then the
DeVaSys board needs to connect to the JP3 connector (see
Figure 11).
The DeVaSys board will need to connect with a 5-pin to 5-pin
point-to-point connector (pin 3 is not used, but the
ADuM1250 uses the 3.3V supply provided by the DeVaSys
board).

EEPROM
For applications that require non-volatile storage or require
calibration and the microcontroller flash is no longer
available, the ISL9208EVAL2Z (Rev A) board provides a
serial EEPROM connection to the microcontroller (see
Figure 11). An example EEPROM device is the AT24C16
from Atmel. This is not populated as shipped and there is no
code in the microcontroller in software release 1.5 to support
this device.
Microcontroller Options
The BKGD connection on the ISL9208 board allows
development of new or modified code for the Freescale
MC9S08QG8 microcontroller, which is supplied on the
board.
