BQ25606 ILIM 配置问题

Hello all,

         我现在不用带协议的快充,我们把D+/D-悬空,然后电流有2A,输入是12V,ILIM电流该怎么计算呢 ?

Hollis Liu:

如果USB检测adapter不成功的话,初始限流根据ILIM电阻计算。

ILIM sets the input current limit. A resistor is connected from ILIM pin to ground to set the input current
limit as IINDPM = KILIM/RILIM. The acceptable range for ILIM current is 500 mA – 3200 mA.
The resistor based input current limit is effective only when the input adapter is detected as unknown.
Otherwise, the input current limit is determined by D+/D– detection outcome.

Hello Hollis,           我在手册上查到的只有最大1.8A的电阻配置,没有看到3200mA的。

Hi调整RILIM看看
