Figure 15. Typical Application of DA9213

Figure 15 shows a typical use case of DA9213 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 DA9213. Three GPI/GPIOs embedded in

DA9213 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
