9 Power Supply Recommendations

The VPWR pin provides power to all the circuitry in the TPD2S300. 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 TPD2S300 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 Dead Battery Use Case in Mobile Devices section for more details.

The VM pin is used to control the resistance of the CC OVP FETs. If only CC analog and PD communications are needed over the CC lines, short this pin to VPWR, and no extra capacitor is needed. However, if wanting to use VCONN on CC, and the lower resistance operation of the TPD2S300 is needed, then VM needs to be connected to its own independent voltage source that is ≥ 9 V and ≤ 22 V. This is usually the 3S or 4S battery in the system. If connected to its own independent voltage source, then VM with need its own 1-µF decoupling capacitor; it is recommended to place this capacitor as close as possible to the VM pin.
