Figure 33 shows a typical use case of DA9211 for the supply of CPU, GPU, or DDR rails. The IC is

enabled and disabled by the main PMIC via IC_EN port as part of its sequencer. Once the IC is

enabled, the CORE application processor enables the buck converter with the EN1 signal and

manages the output voltage selection with the VSEL signal.

The VSEL signal can be shared between the main PMIC and the DA9211. Three GPI/GPIOs

embedded in DA9211 are used in this case:

● GPIO2 signals the insertion of an external charger in the application (through interrupt to the host

processor)

● GPIO3 indicates a power-good-condition, either to proceed with the power up sequence or to

enable an external supply connected to the port

● GPI4 is used for the I2C interface address hardware selection
