Hi,
I have BQ27441-G1B I would like edit charge limit parameter. I find it in document SLUUAC9A at V at Chg Term but I cannot modify it.
I tried edit Design Capacity parameter it is work, but Chgr Term not.
how it works:
1. unseal
2. set config access
3. block data control (send 0x61 0x00)
4. Set data class 82 (0x52) - (send 0x3E 0x52)
5. Set data block ( send 0x3F 0x00)
6. set capacity to 2200mA (send 0x4A 0x08 and 0x4B 0x98) -- It is work
7. set V at Chg Term to 4190(send 0x61 0x10 and 0x62 0x5E) - doesn`t set
I think the problem is with the offset because every parameter from offset 0-31 I possible edit but over 31 doesn`t.
I tried set datablock to 0x3f 0x01 but doesn't work..
Please help what is true register address for Vat Chg Term.
Thank you
