USB-C Controller + Power Switch with HV Protection

General Description

Features

^USB Type-C Compliant DFP Controller

^Standard USB/1.5A/3A CapabilityAdvertisement on

The RT9752 is a USB Type-C Downstream Facing Port

(DFP) controller with back to back power switch which offers

28V tolerance on VOUT pin at off state and 3Arated supply

current for VBUS for USB Type-C applications. The RT9752

have Configuration Channel (CC) function to determine when

USB device is attached. If the Upstream Facing Port (UFP)

is attached using an E-marked cable, the RT9752 also

applies power to VBUS andVCONNpower to the cable CC

pin. The RT9752 also identifies whenType-C audio or debug

accessories are attached. Reverse voltage protection is

provided to prevent reverse current flowing back to input

power supply in a power source swap application.

^VBUS Application and Discharge

^VCONN Application to Electronically Marked Cable

^VIN Supply Voltage Range from 4.5V to 5.5V

^Reverse Voltage Protection with Ultra Fast RVP

Recovery

^Low On-Resistance of the Power FETs

^Programmable Current Limit Level

^High Reliability of High Voltage Power Switch

^UL Approved-E219878

 NemkoApproved-NO110026
