General Description

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.



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.

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.

RT1718S

RT1718S 是集成度很高的 TCPC 控制器，內含符合 IEC-61000-4-2 標準的 ESD 防護單元對 CC/SBU/DP/DM 進行保護。它還集成了可對 SBU1/SBU2/DP/DM 進行過壓保護的開關以避免與臨近的 VBUS 接觸時可能存在的高壓所帶來的傷害，過壓保護能力達 24V，使 DP/DM 可以使用在需要支援高壓的 DCP 埠以實施快充協定。
RT1718S 帶有 GPIO 端子，可對外接 P-MOSFET 進行控制以實現用電端和供電端的 VBUS 路徑控制，亦可通過內部集成的電荷泵驅動外接 N-MOSFET 實現同一功能，也可將其配置為 USB3.0 介面所需要的 DP Mux 控制信號以支援替換模式的啟用。
RT1718S 為 VCONN 開關配備了過壓保護、過流保護、RVP 和欠壓保護。RPD_CC1/CC2 是電池失效模式電阻 Rd 引腳，它們獨立於 CC1/CC2，可滿足不同使用者對系統靈活性的需求。
RT1718S 以 WQFN-32L 4x4 封裝供貨。
