Other Parts Discussed in Thread: BQ32000

Hi Team,

My customer considers to use R2221L for his application.
http://www.ricoh.com/LSI/product_rtc/2wire/r2221/r2221-e.pdf

Is there any TI device that could be alternative?
I would like to suggest TI device to my customer.

Best Regards,

Hi Yaita-San,

I have forwarded your request to other groups in TI that might be more familiar with this product family. You might try posting your query on the Motor Drive & Control forum as well.

Hi Arvind-san,

Thank you for your support.
I found BQ32000 but Vcc is 3～3.6V and supply current seems more than competitor.
I would also like to know if there is any advantage for TI devices.

I really appreciate if your team suggest the device until tomorrow(26 Feburary).
We must inform the device to my customer by that time.

Best Regards,
Yaita

Hi Yaita-San,

Unfortunately, my team will not be much help since none of us are familar with legacy RTC products. I have already forwarded your request to the applications manager of the team that might have some input (based on past experience). Please re-post this query to the motor drives e2e forum and someone might be able to better assist you there.

Regards
