Hi All
One of our wireless short range communication module, its charging behavior is:
0~2.9V trickle charge. seems control by h/w3V~3.8V fast charge. should be initilized the fast charge by s/w.
3.8V~4.2V trickle charge. must be controlled by s/w.Question, why need trickle charge at low voltage range. at 0~2.9V range, the charging LED will not turn on. Why need to turn off ?
One more question, it seems after charging complete, there will be some current drawn, therefore the total voltage of battery will go down, when go down to a threshold it will recharging again.
Any info I can study more ? thank you very much!
Best regards, Boki.
