System Start

Follow these steps to launch the system.
3.1.1 Installing the Hardware
●
Connect the load/charger to be powered between pack+ and pack- on J1
● For demonstration purposes it is possible to use a resistor to simulate a load
●
Connect the battery cell stack to the screw connectors on the demonstration board
● Led 1 indicates the enabled status of the demonstration board (controlled by microcontroller SW)
●
In case of emulating cells such as a voltage divider, apply sufficient voltage (see
page 5)
3.1.2 Number of Cells
It is possible to run the board with a reduced number of cells. The minimum voltage for each IC is 6.9V. Cell 1 and cell 6
(MBAT) have to be connected. The missing cells should be connected to the upper cell potential of the module. For further
information refer to the Atmel ATA6870 datasheet Section 7.3: Reduced Number of Battery Cells Configuration. For the
voltage range see Section 3.3 "Powering the Board" on page
be adjusted (CELLSIC# under General Setting). See
configure the supplied software correctly.
