Other Parts Discussed in Thread: BQ40Z50-R2

Hi,

I come across the JEITA battery charger compliance from TI training video, i would like to know does the JEITA compliance is necessary to get my product get into Japanese market?

Another question, JEITA Compliant is only applicable for standalone battery charger?

Hello,

JEITA compliance is applicable to any charger not just standalone battery charger.

Hi Raheem,

Thanks for your reply.

I do have another one question. If my smart battery is integrated with BQ40Z50-R2 fuel gauge IC, do i still need a charger with JEIDA profile? My guess is any charger will work fine with BQ40Z50-R2 IC right? As long as there is a communication bus (SM BUS and I2C) establish between gauge IC and charger IC, am I right?

Hello Patrick,

If the thermistor is connected to the gauge, you don't need a charger with JEITA. As long as the gauge can communicate to the MCU and the MCU is able to either suspend charge, reduce charge current or charge voltage as stated in the JEITA specification.
