CY2311-USB PD3.0/PPS QC3.0 and Legacy Capability


CY2311-An USB PD3.0 Protocol Controller with Legacy Capability DataSheet 

CY2311 & CY2312 Introduction

GENERAL DESCRIPTION
    CY2311 is an USB Type-C Power Delivery Controller dedicated to power source application with legacy capability. It is compliant with USB Type-C specification rev 1.2 and USB Power Delivery specification rev 3.0 v1.1. CY2311 can support PDO with 20mV/step resolution and 50mA/step current resolution for power management. Also, cable loss compensation, SOP’ commands and Vconn switch with OCP for e-Marker detection are embedded.
    In consideration of customer real application, CY2311 supports options for non-PD protocols like BC 1.2、QC3.0/QC2.0, and Apple legacy modes with auto detection, and maintains backwards compatibility with existing environment. There are rich power-features embedded on the chip, and can be configured through CC channel.
