Connection of PC and Evaluation board

How to start application

Start application

• Click “FGICTool.exe”
  

Select communication type

• Click “Communicate” and select 12C.
  
• Select time interval of log and 12C clock frequency.
  

Register setting

Set Operational mode

• Setting registers
  • Input 115J in the Command field.
  • Input 10001J in the Data field.
    
• Click “Write word”.
  

Set APA

Set APA parameter that is suitable for your battery. Refer the table below about typical APA.

• Setting registers
  • Input 10BJ in the Command field.
  • Input 10000 to FFFF (a value suitable for your battery)J in the Data field.
    Note: For example the set value in APA register is 0x0A0A for 0x0A APA value.
    
• Click “Write word”.
  

Typical APA

Select battery profile

Select and set a profile that is suitable for your battery from the table below.

• Setting registers
  • Input 112J in the Command field.
  • Input 10000 or 0001J in the Data field.
    

Initialize RSOC

Execute RSOC initialization.

• Setting registers
  • Input 107 J in the Command field.
  • Input I AA55J in the Data field.
    
• Click “Write word”.
  

Note: The accuracy of the Initialization requires the OCV reading to be taken with minimal load or charge, under 0.025C, on the battery. (i.e. less than 0.6mA for 24mAh design capacity battery.)

Set Thermistor mode

Select Thermistor mode.

• Setting registers
  • Input 116J in the Command field.
  • Input 10001J in the Data field.
    
• Click “Write word”.
  

Note: This setting is not required if this LSI receives Cell temperature from Master device via 12C.

Set Thermistor B

Set a value that is suitable for your thermistor for TSENSE1, TSENSE2. Refer to the datasheet of the thermistor for the B constant.

• Setting registers
  • Input 106J in the Command field.( 10EJ TSENSE2)
  • Input 1B constant in the Data field.
    
• Click “Write word”.
