The RT1718S is a highly integrated TCPC controller which includes IEC-61000-4-2 ESD protection cell for CC/SBU/DP/DM. The RT1718S integrates several high voltage protection switch of SBU1/SBU2/DP/DM from high voltage VBUS touching the adjacent pins. The AMR of SBU OVP switch is 24V. High Voltage USB 2.0 Switches also support HV DCP and fast charging protocols.

The RT1718S can control VBUS sink and source path by internal Charge pump for NMOS FET and GPIO for PMOS FET. The GPIOs of RT1718S can be also configured to control system block such as USB3.0 to DP Mux for alternated mode usage.

VCONN Switch with OVP/OCP/RVP/UVP protection is also integrated. The RPD_CC1/CC2 are the dead battery mode Rd pin which are independent from CC1/CC2 for each customer system flexibility.

The RT1718S is available in a WQFN-32L 4x4 package.
