BQ25792: BQ25792 can not in shutdown mode

Part Number: BQ25792


Hi

The customer test with the BQ25792EVM, they want to test the shutdown mode, when send the SDRV_CTRL[1:0] to 01, REG11 set to 0x43, the register does not change.

From the datasheet we know that the adapter needs to be disconnected during configuration, otherwise the write value is invalid;

Therefore, when they configure, they use the battery to supply power and disconnect the adapter; This bit value cannot be changed. the other register can change normally.

Why this chip can not in shutdown mode?

Waiting for your reply.

Thanks
