Other Parts Discussed in Thread: BQ25606, BQ25619

Hi Team,

Customer is designing Bq25606 & 24040 charge IC.
Can Bq25606 & 24040 charge IC support JEITA的Function?
Can Bq25606 & 24040 support the NTC voltage read back function? If yes, which register should customer read?

in other word, can BQ25606&24040 meet the following requirement?

0~10℃ 0.2C/4.1V,

10~45℃ 0.5C/4.2V

BQ25606 support JEITA function. According to JEITA, charge voltage folds back to 4.1V for 45C to 60C. For 0~10℃, the charge current is reduced to 20% of ICHG.

Hi Hong,

thanks for feedback.

Can BQ25619 also support the requirement?

for BQ25606, how to set on the design to meet the requirement? Do we have reference design that can meet the requirement?

Hi SHH:

Yes, BQ25619 supports JEITA. For BQ25606, just follow the datasheet and calculate resistor divider on TS pin to program temperature range.

Regards,

Hong
