Original question:
Hello,
I am developing a circuit which involves a Li-ion battery. The battery has to have the ability to charge, that's why I am using BQ25601D, and the processor has to be able to measure battery voltage and current and for that purpose, I am using bq27z561.
I was wondering how to make these two chips work together in the circuit. Do you maybe have any circuit diagram examples?
Thank you sincerely,
Žan
Hi Žan,
The EVM User's Guides have some high-level block diagrams to show how to connect the charger and the gauge. For example, please take a look at Figure 9 from the BQ27z561 User's Guide and Figure 1 from the BQ25601D User's Guide. The battery is connected to the gauge circuit, which is connected to the BAT side of the charger circuit.
I would also recommend ordering these EVMs in order to simplify the evaluation and debugging process.
Best regards,
Angelo
Thank you Angelo!
If I understand this correctly, my circuit should look something like this...?
Also: should I power processor directly from PACK+ and PACk- or should I connect it to SYS_GND?
Thank you,
Žan
