Functional Description

Flexible configurability and the availability of different control schemes make both DA9213, DA9214,

and DA9215 the ideal single/dual buck companion ICs to expand the existing capabilities of a master

PMIC.

Due to the advanced compatibility between both DA9213, DA9214, and DA9215 and the DA9063,

they offer several advantages when they are operated together. These advantages include:

● DA9213, DA9214, and DA9215 can be enabled and controlled by DA9063 during the power up

sequence, thanks to DA9063’s dedicated output signals during power up, and compatible input

controls in both DA9213, DA9214, and DA9215.

● DA9213, DA9214, and DA9215 can be used in a completely transparent way for the host

processor and can share the same Control Interface (same SPI chip select or I2C address),

thanks to the compatible registers map. DA9213, DA9214, and DA9215 have a dedicated

● DA9213, DA9214, and DA9215 support a power good configurable port for enhanced

communication to the host processor and improved power up sequencing.

● DA9213, DA9214, and DA9215 can share the same interrupt line with DA9063.

In addition, the 2-WIRE / 4-WIRE interfaces allow DA9213, DA9214, and DA9215 to fit many

standard PMU parts and power applications.

Figure 14: Interface of DA9213/14/15 with DA9063 and the Host Processor

As shown in Figure 14, a typical application case includes a host processor, a Main PMIC (for

example, DA9063) and DA9213 or DA9214 or DA9215 used as companion IC for the high power

core supply.

The easiest way of controlling DA9213, DA9214, and DA9215 is through the Control Interface. The

master initiating the communication must always be the host processor that reads and writes to the

main PMIC, and to the DA9213, DA9214, and DA9215 registers. To poll the status of DA9213 or
