Why the BQ4802Y Clock is not keep clocking when system power down ?
I have setted /STOP=1 in cotrol register E and use CR2302 Li Battery for Vbc. but the clock is not continue clock while system power down.
I've checked the BVF flag…
Part Number: BQ4802Y I've use BQ4802Y as system real time clock. VCC is 5VDC, VBC=3VDC Li Battery. I set the /STOP=1 in control register(E) and ABE=1 in Alarm enable register(C). I've checked that Control Register(E) content=06h, Flags Register(D) content…

BQ32000DR SOIC-8, please confirm which one is currently recommended by TI's original manufacturer with similar specifications and whether there are new products.
Part Number: BQ4802Y Greetings
I need to implement a Real Time Clock in an Arduino UNO design and A Raspberry PI design.
Although the use is not the same in each, the general scenario is to just assign a Date / Time Stamp to a specific event.
The preferred…
Other Parts Discussed in Thread: BQ4802Y Good morning
Is it possible use the BQ4802Y without the external NVSRAM?
Are there some issues to consider?
Thanks for your support.

Hi Y.Ottey,
There are some RTC devices with lower specified backup supply current, but they are much older than BQ32002 and would have other differences such as serial/parallel programming rather I2C. These devices include BQ3285, BQ4802Y, or BQ4845,…
Part Number: BQ4802LY Other Parts Discussed in Thread: BQ4802Y Hi All,
I have a question about BQ4802.
Is access disabled when Low is input to the CSIN pin? The CSIN pin is a chip select pin. Can CSIN control enabling and disabling access to the RTC?
