SLVUBX5B August 2023 – February 2024 TPS25762-Q1 , TPS25772-Q1
VIN Engine On or Off power level parameters are configurable in this page.
The TPS257xx-Q1 family supports autonomous power transition dependent upon the VIN (for example, VBATT) voltage level per the diagram shown in Figure 4-4.
The Engine On/Off voltage thresholds must be configured in sequential order (highest to lowest): EngOnVth (full power) > EngOffNomVth (low power) > EngOnMinVth (low power) > EngOffMinVth (disabled).
Maximum power for the low-power phase is a configurable total port power output. Program maximum power relative to total VBUS power.
