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

Figure 15: Typical Application of DA9214

Figure 15 shows a typical use case of DA9214 for the simultaneous supply of a CPU and a GPU rail.

The IC is always enabled because IC_EN is shorted to the battery voltage. The CORE application

processor enables and disables the CPU/GPU and the DDR individually via dedicated ports on

DA9214.
