BQ32002: Interrupt Output every 24 hours

Koshi Ninomiya

Part Number: BQ32002
Other Parts Discussed in Thread: TPL5010

Hi Team,

Can we use BQ32002 as a device which does interrupt output every 24 hours?
If yes, how do we set the BQ32002?
If no, could you suggest another solution?
Thank you.

You could set FT = 0 and configure the IRQ pin to output the OUT logic level. See datasheet Table 11 for more information.

TPL5010 is a good alternative for this application, but it only can generate the interrupt every two hours.

Kind regards,
Lane

Hi Lane-san,

Thank you for your reply.
By what condition does the OUT bit of CAL_CFG1 Register change the value between "1" and "0" under the FT="0"?

Hi Lane-san,

Please let me know by what condition the OUT bit of CAL_CFG1 Register changes the value between "1" and "0" under the FT="0".
Thank you

Hi Koshi,

The OUT bit will change by direct I2C write

Kind regards,

Hi Lane,

I got it. So, there is no device which can generate the interrupt every 24 hours.
Thank you.
