Hello,
I have huge problem with radiated EMI with BQ40z60 charger and I plan to seperate BMS IC and charger IC. What more, I have very limited space on PCB, so please advice. My requirements are
- 2S3P battery pack
- 12V input voltage
- 1.5 A charging current
- low switching frequency (the lower frequency, the less EMI problems - is that correct?)
- integrated switching MOSfets (integrated MOSfets will radiate less than external - is that correct?)
I will be thankful for answer and advices. The problem is urgent for me.
Best,
Karol
