Other Parts Discussed in Thread: BQSTUDIO
Hi there,
Recently I had purchased a BQ25713 EVM and had tested the working of the same with the help of the guide given out by the TI.
The datasheet of BQ25713 was referred to set the configuration to the EVM. The complete working of the EVM with a battery pack and system was tested and verified.
After understanding the working, We have developed custom board using BQ25713 as exactly as EVM schematic, which has been posted below.
The issue I am facing now in the bqstudio is that the input voltage register is not getting updated to the value I want to set but rather stays at the POR value every time I read the register value. I have followed the same exact steps that was followed to set up the EVM board which works completely fine but it does not help here with my pcb. Started with ensuring the low power mode is switched off in the chargeoption0 register, then setting up the charge voltage and current register to start charging but with no good result. The ADC register was set just after the setting up of the chargeoption0 register.
The result of which, I am not able to charge the battery pack even though I am able to write the battery charging current register. Also we can notice that the Charge status register shows the presence of Adapter and there are no faults displayed. The screenshot of the same has been provided below.
I wanted to know where am I going wrong with the procedure of setting up of the charger in our custom board.
