4.6.1 System Power Management

System Power Management (SPM) parameters can be configured in this page. Three SPM policies available:

  • Assured Power - Maximum Init Power
    • Initially allocates maximum power per port without power sharing
  • Assured Power - Minimum Init Power
    • Initially allocates minimum power per port without power sharing
  • Shared Capacity - Fair Share Power Policy
    • Enables power sharing between ports (only applicable in a two port system)
    • When selected, an option to enable or disable blind sink support is active.
    • When blind sink support is enabled, an additional option to enable or disable "Max Power" is active. This will enable the charging port to offer max power to the sink regardless of behavior.

This feature works in conjunction with the configured port power parameters.

For more information regarding SPM, see the TPS2576x/TPS2577x-Q1 Source Power Policy Management.
