Hi 

I am using B0510-2R5224-R (Supercapacitors / Ultracapacitors .22F 2.5V EDLC B SERIES CYL) supercapacitor for backup.

Is this will work or suggest me a supercapacitor to use with BQ32000.

THANK YOU.

Tool/software:

The BQ32002 (and BQ32000) has separate registers for parts of date and time, all which can be read and written separately over I2C.

But if separate I2C accesses are made, and the…

Hi, Support Team

We would calculator BQ32000DR about Power Dissipation.

PD=(Tj-Ta)/ ThetaJA=(150°-25°)/114.8=1.08W

is correct?

if any suggestion, Please advise me.

Thanks,

Hello expert,

May we know if there is leakage current flows through all the switch from Vback to VCC? Customer would like to save power from VBACK and don't want leakage for it.
