Question:
For the MAX77734, MAX77650, MAX77651, and MAX77278 linear battery charger safety timer (tFC), what is the update condition?
Answer:
The fast-charge safety timer is intended to be set once (by initialization firmware) before charging begins and remain unchanged throughout the charge cycle. Therefore, if a new timer period is set (T_FAST_CHG[1:0]) during charging, no immediate update takes place. The new timer setting is used the next time the charger enters fast-charge (CC) mode.
