For the firmware settings needed for the design
requirements, refer to the BQ27Z746 Technical Reference Manual.
- To change design capacity, set the data flash value (in mAh) in the Gas Gauging: Design: Design Capacity register.
- To set device chemistry, go to the data flash
I2C Configuration: Data: Device Chemistry.
The BQStudio software automatically populates the correct chemistry
identification. This selection is derived from using the BQCHEM feature in the
tools and choosing the option that matches the device chemistry from the
list.
- To set the design voltage, go to Gas Gauging: Design: Design Voltage register.
- To set the cell Low Voltage or clear the cell Low
Voltage, use Settings: Configuration: Init Voltage Low
Set or Clear. This is used to set the cell voltage
level that will set (clear) the [VOLT_LO] bit in the Interrupt
Status register.
- To enable the internal temperature and the external temperature sensors: Set Settings:Configuration: Temperature Enable: Bit 0 (TSInt) = 1 for the internal sensor; set Bit 1 (TS1) = 1 for the external sensor.
