ZHCSKK3B December 2019 – February 2022 TPS6594-Q1
PRODUCTION DATA
A power sequence is an automatic preconfigured sequence the TPS6594-Q1 device applies to its resources, which include the states of the BUCKs, LDOs, 32-kHz clock and the GPIO output signals. For a detailed description of the GPIOs signals, please refer to Section 8.3.7.
Figure 8-45 shows an example of a power up transition followed by a power down transition. The power up sequence is triggered through a valid on request, and the power down sequence is trigger by a valid off request. The resources controlled (for this example) are: BUCK3, LDO1, BUCK2, LDO2, GPIO1, LDO4, and LDO3. The time between each resource enable and disable (TinstX) is also part of the preconfigured sequence definition.
When a resource is not assigned to any power sequence, it remains in off mode. The MCU can enable and configure this resource independently when the power sequence completes.
As the power sequences of the TPS6594-Q1 device are defined according to the processor requirements, the total time for the completion of the power sequence varies across various system definitions.
