BQ24157设置充电电流650mA没有效果

Other Parts Discussed in Thread: BQ24157

在使用BQ24157的过程中,初始化充电电流设置为650mA,limit电流为800mA,但是实际测试到充电电流只有550mA。

使用I2C读取寄存器的值如下:

BQ2415X_REG_STATUS 0 0x40
BQ2415X_REG_STATUS 1 0x68
BQ2415X_REG_STATUS 2 0xbe
BQ2415X_REG_STATUS 3 0x51
BQ2415X_REG_STATUS 4 0x18
BQ2415X_REG_STATUS 6 0x7c

请问如果需要充电电流大于550mA,需要怎样设置寄存器
