BQ24157寄存器配置不成功

Other Parts Discussed in Thread: BQ24157

该芯片的两个寄存器配置不成功,具体如下:

1、04寄存器:写入值为“01110001”,结果读取此值为“01001001”,导致实际充电电流不对

2、06寄存器:写入值为“10000010”,结果读取此值为“01000000”

其他寄存器没有以上问题,请帮忙解答,谢谢!

  • First, bq24157 pin E2 is input pin CD (charge disable) while bq24150 pin E2 is output AUX PWR. Second, registers 1 - 4 are the same for the two parts and so the same code should work.. Register 5 of bq24157 includes control of the VINDPM feature of the bq24157 and status of the DPM loops, which might be helpful. Of course, if you need to charge higher than 4.2V or increase the maximum charge current, you will need to write to Register 6 immediately after power up before writing to any other register.
  • 感谢您的回复!

    现在Register1-5配置正常.但Register 6还有问题,我们对Register 6是一上电就第一个配置,但写入的值是0X82,而写完读出的值是0X72,请问可能是什么原因呢?谢谢!
