ACTIVE

The RT1718SGQW is a USB Type-C controller that complies with the latest USB Type-C and PD standards. This document explains the function and use of the RT1718SGQW evaluation board (EVB), and provides information to enable operation, modification of the evaluation board and circuit to suit individual requirements.

General Description

Performance Specification Summary

The RT1718SGQW is a USB Type-C controller that complies with the latest USB Type-C and PD standards. The RT1718SGQW integrates a complete Type-C Transceiver including the Rp and Rd resistors. It does the USB Type-C detection including attach and orientation. The RT1718SGQW integrates the physical layer of the USB BMC power delivery protocol to allow up to 90W of power and role swap.

Table 1. RT1718SGQW Evaluation Board Performance Specification Summary

Key Features	Evaluation Board Number: PCB123_V1
Default Input Voltage	45W PD TA or higher at USB2 (Type-C connector, “Adapter”)
VBUS Output Current	5A at UAB1 or U411
VBUS Voltage	5V to 20V at UAB1 or U411
Default Marking & Package Type	RT1718SGQW, WQFN-32L 4x4 (W-Type)
Operation Mode	Normal Mode: DRP, Dead battery. Meter Mode

Operations

The RT1718SGQW EVB supports two modes. The one is normal mode (hardware default) where USB1 and U411 are DRP when there is PD TA (45W or higher) at USB2, or USB1 and U411 are dead battery when there is no PD TA (45W or higher) at USB2. The PD power at USB1 or U411 will be less than the power of PD TA at USB2 by 10W. Please do not connect to two devices at USB1 and U411 under normal mode operation. The other one is meter mode where the VBUS voltage and VBUS current (the current direction from U411 to USB1 is positive) of two PD devices at USB1 and U411 are reported on Display. In meter mode, PD TA at USB2 is not nessecary.

The following table shows the settings for normal mode and meter mode.

Mode	CP3	CP4	CP13	CP14
Normal Mode (Default)	Short	Short	Open	Open
Meter Mode	Open	Open	Short	Short

By pressing SW1, MCU will be reset.

SW2, SW4, SW5, and SW3 work only under normal mode.

Button	Function	Behavior
SW2	Request Previous PDO	RT1718SGQW as sink will request the previous PDO in Source PDO order by pressing this button.
SW4	Vconn Swap	RT1718SGQW will send Vconn Swap message to port partner.
SW5	Request Next PDO	RT1718SGQW as sink will request the next PDO in Source PDO order by pressing this button.
SW3	Power Role Swap	RT1718SGQW will send Power Role Swap message to port partner. If there is no PD adapter at USB2 (45W or higher), there will be no action by pressing this button.

The display shows the information according to the setting and attachement as the following table. By each pressing SW6, the information will be shown in sequence.

Mode	USB2	USB1 or U411	Display information in sequence.
Normal Mode	No TA	No Attached	NA
Normal Mode	No TA	Attached	1. Power Role, Vconn on/off 2. PD Contract 3. Vbus Status (real vbus voltage and current) 4. Remote SRC Cap 5. Remote SNK Cap
Normal Mode	TA	No Attached	1. DRP, Unattach 2. TA Power. Vbus voltage, current (Contract)
Normal Mode	TA	Attached	1. Power Role, Vconn on/off 2. PD Contract 3. Vbus Status (real vbus voltage and current) 4. Remote SRC Cap 5. Remote SNK Cap 6. Cable Info (if there is e-mark IC in cable.) 7. TA Power. Vbus voltage, current (Contract)
Meter Mode	Don not care	Two devices attached at USB1 and U411.	Real Vbus voltage, current

LED2 will light up if the power of TA at USB2 is lower than 45W.

RT1718S

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.
