BQ2060 Pin Vout For external EEPROM Power supply by 1058677
In the mass production, There usualy a qution that some contents in eeprom is changed..
One addresses is 0x08-0x0b as the follow picture...
The Misc Options is usualy changed into FF.. Safety Overtemperature is changed into 69. Charging Volatge is changed into65535...In addtion,these addresses is changed at the same time.
Another Addresses is 0x3a to 0x3f..
Pack Capacity is usualy changed into 65535....
If i try write the correct value in these address , and send the initial command. the bq2060 could not be initialed normally..For example, the Pack Capacity is changed to 65535. Now i wirte 4500 to the Pack Capacity and initial the bq2060.. The reletive of charge is 100%, not 0%..
1. The bq2060 read the configure value in EEPROM at the initial time, at other times,BQ2060 just update the cycle values, why the Misc Option and Pack Capacity .etc are changed?
2.I have read through the bq2060a datasheet.and there isn't explanation about the Pin Vout(Pin 6 in ba2060a). How long about the Vout supplying to EEPROM while writing cycle value..
3. The recommended EEPROM is 24lc01B of Micro Chip and Atmel. the max writting period is about 5ms..Can it meet the Vout inbq2060 time supplying power to EEPROM while writting...
