Operational Steps

To initiate an automatic charge cycle, one assumes that a fully discharged battery (V
inserted.
Also the TA needs to be inserted to J1 – there is no order in which the battery or TA needs to be
inserted first.
In addition, J60 must be connected to the USB port of a computer for I2C communication using the
DA9318 Reference Board

Both jumpers on J15 and J18 must not be fitted. The battery +/- senses must be connected to J16 (+ sense) and
J19 (- sense).
The steps to operate the automatic charge cycle are highlighted in
1. Check out the battery charge voltage (see battery information) and set the Main CV accordingly.
2. As required, check out and modify the Auto Charging parameters in the Options → Settings
window – see paragraph 7.3.2.1.
3. Click the Auto Charge button, to start the automatic charge cycle.
The charge cycle (i.e. plotting the battery voltage and charge current) is shown by the Profile Plot of
the Real-time Charging Performance Graphs.
The main charger and DA9318 efficiency is shown by the Efficiency Plot; whereas the DA9318 die
temperature is shown by the Temperature Plot.
