INTRODUCTION

2.1

General Description

The UPD360 is a highly integrated, small form factor USB Type-C Power Delivery (PD) Port Controller designed to

adhere to the USB Type-C™ Cable and Connector Specification and USB Power Delivery 2.0 Specification. The

UPD360 provides cable plug orientation and detection for a USB Type-C receptacle and implements baseband commu-

nication with a partner USB Type-C device via the integrated USB Power Delivery 2.0 MAC. The device can function in

Standalone UFP/DFP modes, or utilize the integrated I2C/SPI interface to connect to a companion CPU/SoC (depen-

dent on device version, see Section 2.2, "UPD360 Family Differences Summary").

Additionally, the UPD360 integrates many of the analog discrete components required for USB Type-C PD applications,

including two VCONN FETs with Rp/Rd switching, a port power controller that supports up to 5V/3A on VBUS, and cur-

rent and voltage sense circuitry for over-voltage/current detection. By integrating many of the analog discrete compo-

nents required for USB Type-C PD applications, the UPD360 provides a low cost, low power, small footprint (4 x 4 mm)

solution for consumer (notebooks, desktop PCs, smartphones, tablets, monitors, docking stations) applications.

To enable the UPD360 to efficiently support dead battery use cases, an integrated power switch is provided to select

between two external 3.3V supplies (VBUS and main). This effectively allows connection detection and system wakeup

without external processor intervention (external processor in sleep mode).

The UPD360 is also capable of negotiating alternate modes over USB Type-C connectors using the Power Delivery 2.0

protocol. Both DisplayPort and Thunderbolt operation over USB Type-C connectors are supported in addition to other

major protocols.

A system diagram utilizing the UPD360 is shown in Figure 2-1. An internal block diagram of the UPD360 is shown in

Figure 2-2.
