Other Parts Discussed in Thread: BQ25180
Hi,
I have a BQ25180EVM. I have a lot of problem with it.
Firstly, I cannot use this EVM in SYS_MODE - 01.
I connected my battery, it has 4.2 V.
I opened my Power Supply, it is in 5 V
I sent this comment, myI2C_write(SYS_REG, 0x44); with STM32 MCU.
I observed that Vsys decreased 4.2 from 5 V in my Oscilloscope.
When i close down the power supply, Vsys is also decreased 1.77 V.
Is it a wrong application? What should i do for powering Vsys from battery?
