Hello Syed,

Yes, I2C works during DEEPSLEEP mode. However, no measurements are taken in DEEPSLEEP mode. For a more detailed description of DEEPSLEEP, you can read Section 7.4 of the BQ76952 Technical Reference Manual.

Hi thanks for your response.

Does control status command (0x00) [DEEPSLEEP] bit sets to 1 during deepsleep mode?

can we able to read the control status command by 12C during deepsleep?

Hello Syed,

Bit 2 in the control status register would be set when the device is in DEEPSLEEP (See Section 12.2.1 of the TRM), you should be able to read this with I2C.
