I Want to used a single chip to deal handheld device power manger.
Battery is 1 cell li-lon(3.7V).
It's a verification project.
we used atmel406 to deal these thing.But when used 1 cell , It wasteed too much(space and peripheral device).
I read some ti sigle cell li-lon battery power solution.Chose the bq2416x series or bq2418xseries to deal with.
My question shows in below,Thks for your help:
1.The inter register address.In databook(http://www.ti.com/lit/gpn/bq24160), It only said "The device 7-bit address is
defined as ‘1101011’ (6Bh)." I could not locate the any reg by this information.e.g:If i want to access Control/Battery Voltage Register, what address i send on i2c;
2.I couldn't find a softmanual databook , soft flow chart or example. I mean if i used a device to access bq24xxx,Set parameters , which regiseter i set first? And if i set new value ,when it work in new parameters?
3.In databook(http://www.ti.com/lit/gpn/bq24160), Fig3 shows GSM PA direct connect to battery.If in this operation,The GSM PA always worked. And the PA power did not regulate by ldo or others device.It work correct ? As Fig4,The PMOS can connect to BGATE without any other operation?
4.In bq24180databook ,If Battery directly connect to sys_load,How did i control battery pump power? I means it would be always worked,until power below my systm power.
