PRODUCTION DATA
The VPWR pin provides power to all the circuitry in the TPD4S311. It is recommended a 1-µF decoupling capacitor is placed as close as possible to the VPWR pin. If USB PD is desired to be operated in dead battery conditions, it is critical that the TPD4S311 share the same power supply as the PD controller in dead battery boot-up (such as sharing the same dead battery LDO). See the CC Dead Battery Resistors Integrated for Handling the Dead Battery Use Case in Mobile Devices section for more details.
