Some questions about BQ25120A
Our customer demand
0-15 charging current: 10ma
15-45 charge 1 c = 60 ma
The specification book has a TS FAULT state as follows
When TS FAULT is 11, 11 -- TWARM <TS temp & lt;THOT (voltage reduced by140 mV)
A: what is the meaning of this state? Does the software need to intervene?Turn off charging at this state?
Ii. According to the temperature range (0-15-45) required by the customer, there are two Settings:
1: set COLD to 0 degrees and HOT to 45 degrees
So when TS FAULT= 10, does that mean the temperature is 0 to 10 degrees?
Now the charging current is half of the fast charging current, right?
If TS FAULT = 11, does that mean the temperature is 30 to 45 degrees?
What is the charging current?
2: set COLD to 0 and HOT to 60
If TS FAULT = 11, does that mean the temperature is 45 to 60 degrees?
If the main control software is not involved, how much is the charging current?
If at this time, the master control closes the charging through I2C control of BQ25120A, does it mean that the charging will stop at 45 degrees, just to meet the customer's demand
Whether the above understanding is correct, suggest us to choose which plan is good?
