|
TPS6594 is a Power Management IC which provides regulators and others
|
|
features like GPIOs, RTC, watchdog, ESMs (Error Signal Monitor), and
|
|
PFSM (Pre-configurable Finite State Machine) managing the state of the device.
|
|
TPS6594 is the super-set device while TPS6593 and LP8764 are derivatives.

Identify the primary PMIC on SPMI bus.
|
|
A multi-PMIC synchronization scheme is implemented in the PMIC device
|
|
to synchronize the power state changes with other PMIC devices. This is
|
|
accomplished through a SPMI bus: the primary PMIC is the controller
|
|
device on the SPMI bus, and the secondary PMICs are the target devices
|
|
on the SPMI bus.
