BQ3055 Battery Management and Charging

Vikram,

We have a MathCAD tool that can help to set the CEDV coefficients and it can be found on the bq3060 website.

We do not have specific recommendations for thermal cutoff fuses, but there are several manufacturers who make them a couple are discussed on this link.

Murata also has a line of thermal cutoff fuses.

Hi Tom,

We need to program the data flash of BQ3055 using the MSP430. There is no DataFlashSubClassID or DataFlashSubClassPage1..8 stated in the BQ3055 RM.

Also there are no offset specified for each of the parameters.

Can we use  the BQ3060 as reference to program the data flash of BQ3055 through MSP430 using the offsets and subclasses given in BQ3060RM. 

Vikram,

The DataFlashSubClass method is not applicable to the bq3055. It uses a different method. See Appendix C of the TRM. 

Regards

Tom

Hi Tom,

In the BQ3055 TRM, "DFRowAddress(0x01yy)", what does the yy corresponds to ?

What is the "Variable Offset" values to be considered for each of the parameter (ie. CC Gain, VC2 K-factor, etc).

Vikram,

The data flash memory is divided into 32 bytes blocks. The yy corresponds to the sequence of blocks starting with 00 and counting to 3F in hexadecimal.

Tom
