I have doubts about the behaviour of bq24250 and bq24250C:
1.- If I put /CE pin HIGH the charge is disabled. I want to put this pin to a fixed HIGH level and start charging only via I2C. The idea is that the charging is disabled at power up and the only way to start charging will be via I2C. I think this will work, but what happens if the watchdog timer expires? The datasheet states that if watchdog timer expires the charger will enter DEFAULT mode, so when enters this mode, the charge will be disabled again?
1.- This charger has a modified JEITA charging profile. I want to fix the Thot temperature to 45 celsius degrees instead of 60. If I modify this temperature to 45C, the Tcool wil be modified as well. This is not a problem, because for me it is better if Tcool is closer to the standard JEITA (about 10C). With a 10k NTC resistor and beta close to 3500K, Tcool is about 17.5C. This works well for me, but I want to know if I can do this modification and that it will not cause any problem.
Thank you in advance.
