SLVAFG6A December 2022 – November 2023 TPS25762-Q1 , TPS25772-Q1
The TPS257xx-Q1 PD controllers support Power Foldback Policies based on system temperature and VIN supply voltage levels. The Power Foldback Policies are managed by the integrated SPM Engine alongside the Multi-Port Power Allocation Policy (in the case of the TPS25772-Q1). Upon entry into a Power Foldback condition, the SPM uses the Total USB VBUS Power for the corresponding Power Foldback phase the TPS257xx-Q1 has entered then distributes port power accordingly.
