Hi Sir,
WOuld you pls help questions for bq24078, thanks.
a)What would be the maximum fast charge current allowed to be set under USB500 mode?
b)When the Riset of EVM is set to be 1800ohms, the max fast charge current is about 470mA,
Is it because the limitation of the Kiset(max)?
c) by using the BQ24078 evm to charge a 2500mAH battery,(Riset =2K ohms to achieve 450mA fast charge current)
the fast charge process took about 5.5hrs,
and the constant voltage charge process took about 1hrs to reach Iterm to trigger the /CHG(red led) to be turned on.
Is it common to have a 1hrs+ constant voltage charging process by using BQ24078 charger ic?
Thanks, Ian.
