RT1737

USB-C Protection Solutions for Signal Path, CC OVP Switch,

VCONN Switch, SBU OVP 1:2 Switch and USB2.0 Switch with

BC12 and Charging Port Configuration

Features

General Description

⚫ 6-Channel of short to VBUS Overvoltage

Protection (CC1_CON, CC2_CON, SBU1_CON,

SBU2_CON, DP_CON and DM_CON)

⚫ 60ns Ultra-Fast OVP Response Time of

DP/DM/CC/SBU

The RT1737 is a highly integrated USB-C Protection IC

which includes IEC-61000-4-2 ESD protection cell for

SBU/DP/DM. The RT1737 integrates high voltage

protection switches for DP/DM/SBU1/SBU2/CC1/CC2

to prevent high voltage VBUS from touching the

adjacent pins. The AMR of DPDM/SBU/CC OVP

switches is 28V. High Voltage USB 2.0 Switches also

support SDP/DCP/CDP configuration.

⚫ High Absolute Maximum Ratings = 28V of

CC1_CON, CC2_CON, SBU1_CON, SBU2_CON,

DP_CON, DM_CON

⚫ DP/DM USB2.0 Switch with 3dB BW of 800MHz,

High Voltage of 21V Protection and Supports

Charging Port Controller for SINK and SRC Port

(BC1.2)

The RT1737 also integrates SBU 1:2 OVP Mux for

specific application like debugging mode, factory mode,

etc.

VCONN Switch with OVP/OCP/RVP/RCP/UVP

protection is also integrated. The RPD_CC1/CC2 pins

function as the Rd pin in dead-battery mode and are

independent of CC1/CC2, which provides each

customer system with flexibility.

⚫ SBU OVP with 1:2 Mux Selectable

⚫ 4-State ADDR pin for Multiport Application

⚫ Dead Battery Mode Support

⚫ VCONN Switch Integrated with

OVP/OCP/RCP/UVP/RVP Protection

⚫ IEC61000-4-2 Contact Discharge Protection

 DP_CON/DM_CON: 8kV

The RT1737 is available in a WQFN-32L 5x5 package.
