RT7800B

AnyPower^TMand PDsafe^TMUSB Type-C PD Controller

General Description

Features

^AnyPower^TM=AnyVolt^TM+ AnyCurrent^TM

The RT7800B is a USB PowerDelivery (USB PD) controller

with highly integrated functions for notebook, tablet, mobile

phone or any other devices with USB Type-C (USB-C)

receptacle. It is designed to embed ARM Cortex^TM-M0

MCU so as to facilitate various functions of communication

protocol, protections and customized requirements. The

IC allows designer to define a USB-C port as a Provider,

Consumer or aDual Role Port by program setup.

^AnyVolt^TM(50mV/step) Output Voltage Adjustment

for USB Cable Bus Power (V_BUS

)

^Support Internet Online Firmware Updates

^AnyCurrent^TMOCP for USB-C VBUS Output

^Cable Voltage Drop Compensation (CDC) for V_BUS

^Support Provider, Consumer and Dual Role

Compliant with USB Power Delivery 3.0

Specification
