Richtek's RT1718S TCPC features IEC-ESD protection, USB2.0 switch, charging port controller and power path control

Nov 13 2022 2022-11 Sensors Richtek USA Inc.

Richtek's RT1718S Type-C Port Controller (TCPC) controls the VBUS pull and feed path via NMOS FET's internal charge pump and PMOS FET's GPIO. The GPIO of the RT1718S can be configured to control system modules such as USB3.0 to DP multiplexers for alternate mode use.

The RT1718S is a highly integrated TCPC controller in a WQFN-32L 4x4 package. Includes IEC-61000-4-2 ESD protection unit for CC/SBU/DP/DM. The RT1718S integrates multiple high-voltage protection switches from the high-voltage VBUS SBU1/SBU2/DP/DM, reaching adjacent pins. The AMR of the SBU OVP switch is 24V. The high voltage USB 2.0 switch also supports high voltage DCP and fast charging protocol.

The RT1718S can control the VBUS receiver and source path through an internal charge pump (NMOS FET) and GPIO (PMOS FET). The RT1718S gpio can also be configured to control system blocks such as USB3.0 to DP Mux for alternate mode use. The VCONN switch with OVP/OCP/RVP/UVP protection is also integrated. RPD_CC1/CC2 is a dead battery mode Rd pin that is independent of CC1/CC2, providing flexibility for each customer system.
