BQ40Z60: how do i make 'Standard Low Charging Voltage' and 'Standard Hi Charging Voltage' different?

Part Number:BQ40Z60

Hi, 

seems with all the possible charge programming possibilities there is one missing...

Here is what i would like to do:

0C to 10C, Charge Voltage = 4.20V

10C to 45C, Charge Voltage = 4.20V

45C to 50C, Charge Voltage = 4.15V

50C to 60C, Charge Voltage = 4.1V

I'd like to make Standard Low Charging Voltage and Standard Hi Charging Voltage different but there seems to be only one voltage setting for both(??)

SLUUA04D, Figure 4-4 shows 5 Constant Current Mode Matrix columns:

- LT, Low Temp

- STL, Standard Temp Low

- RT, Recommended Temp

- STH, Standard Temp Hi

- HT, High Temp

and

bqStudio/ DataMemory/ Advanced Charge Algorithm/ shows 4:

- Low Temp Charging

- Standard Temp Charging  (?Lo& Hi?)

- High Temp Charging

- Rec Temp Charging

Our Panasonic NCR18650B battery can use separate Standard Temp Charging voltages for the Lo = 4.2V & Hi =4.15V

any ideas how to over come this issue other than making the Lo = 4.15V like Hi = 4.15V for a narrow temperature range (10C to 12C)?

I'm under the impression T1 -> T2 -> T5 -> T6 -> T3 -> T4-> need to be increasing (can T2 = T5?? = 10C)

am i missing something?

thanks,

Tom
