Tool/software:
I am attempting to utilize the balancer 5 click( Balancer 5 Click | Mikroe) which utilizes the BQ25887 in one of my projects. I am using it as a breakout board with my Arduino. The Arduino has successfully identified this board through i2c. I have linked two lithium-ion batteries to the BATT1 and BATT2 terminals. Furthermore, a 5V 3A standard USB adapter is connected to the external USB power supply input of the breakout board. The 5V and GND are connected to the corresponding pins on the Arduino. To monitor the input current for charging from the power supply adapter, I integrated a USB power monitor in series between the power adapter and USB cable.
Unexpectedly, the USB power monitor is indicating 5V and 0A. Could you advise on what might be the issue? Is it necessary to initialize the charging process through i2c initially? No code has been uploaded to the Arduino for the charging process.
For trouble shooting, I have connected the INT pin and the PG pin to an oscilloscope. I am attaching the graph here. The yellow signal(INT PIN) is a square wave with 20hz frequency and the pink signal(PG PIN) is a square with 10hz frequency. Please guide where I am doing it wrong
