Our customer would like to use bq51050 with NiMH battery. Is this possible?

If it is possible, do you have recommended circuit? Please let me know if you have any information.

The battery regulation voltage is very different and it is not realistic to use bq51050 to charge the NiMH battery.

Thanks,

Wenjia-san,

Thank you for your reply. I understood your comment.
Should our customer use wireless receiver (bq51013B etc...) + NiMH charger device if they would like to use NiMH battery?
They requires 4W over power output. In this case, is bq5013B recommended device?

Sasaki-san,

Yes, customer may use a wireless receiver + NiMH charger in their application. The wireless receiver will only be used as a power supply. If the power level is 4W, bq51013B and bq51020 can both be candidates.

Thanks,

Wenjia
