Two-port USB-C controller with Thunderbolt 3 support

A USB-C controller with power delivery (PD) from Cypress Semiconductor has been optimised for Thunderbolt notebook and desktop PCs, as well as docking stations.

The EZ-PD CCG5 controller is said to be the first two-port USB-C controller that supports the Thunderbolt alternate mode.

According to the company, the controller enhances the plug-and-play USB-C user experience, while providing BOM integration with features such as built-in protection against shorts and electrostatic discharge.

To increase the reliability of a system, the device integrates flash memory that can store two firmware images for fail-safe boot. It also offers the EZ-PD family’s programmability to keep up with evolving industry standards.

The one-chip solution minimises costs by integrating 20V regulators, sideband muxes, USB high speed muxes, high voltage power FET gate drivers, VBUS-short protection for configuration channel and SBU pins, dedicated hardware to protect the system against overvoltage, undervoltage and overcurrent fault conditions, and system-level electrostatic discharge protection.

The EZ-PD CCG5 integrates an ARM Cortex-M0 and 128KB flash with read-while-write functionality for firmware upgradeability.

The two-port controller is now sampling in a 96-BGA, 6 x 6mm package, and the one-port version is sampling in a 40-QFN, 6 x 6mm package.
