The RT1718S is a highly integrated TCPC controller that incorporates IEC-61000-4-2 ESD protection cell for CC/SBU/DP/DM. The RT1718S integrates several high voltage protection switches for SBU1/SBU2/DP/DM to prevent high voltage VBUS from touching the adjacent pins. The AMR of the SBU OVP switch is 24V. HV DCP and fast charging protocols are integrated into the high voltage USB 2.0 switches.The RT1718S can control the VBUS sink and source path by an internal charge pump for NMOSFETs and GPIO for PMOSFETs. The GPIOs of the RT1718S can also be configured to control system blocks such as USB 3.0 to DP Mux for alternate mode usage.A VCONN switch with OVP/OCP/RVP/UVP protection is also integrated. The RPD_CC1/CC2 are the dead battery mode Rd pins, which are independent from CC1/CC2 for each customer’s system flexibility. The RT1718S is available in a WQFN-32L 4x4 package. The recommended junction temperature range is -40°C to 125°C, and the ambient temperature range is -40°C to 85°C.
