Cypress Semiconductor recently announced the availability of a compact and highly integrated USB-C controller optimised for passive Thunderbolt and non-Thunderbolt USB-C cables. The EZ-PD CMG1 single-chip solution enhances robustness while reducing bill-of-material costs by integrating high-voltage short protection and system-level electrostatic discharge (ESD) protection.
The controller is fully compliant to the USB Type-C 1.3 specification, ensuring a plug-and-play user experience with the multiple protocols supported by USB-C, along with the fast charging of the USB Power Delivery (USB PD) 3.0 standard. The controller is available in a tiny chip-scale package measuring 1,85 mm² that is ideal for 2,4 mm thin USB-C cable connectors.
The EZ-PD CMG1 protects its CC and VCONN pins against accidental shorts to high-voltage VBUS, which may go to 20 V or higher. The controller offers an operation range down to 2,7 V, enabling a USB-C cable to be powered by a single-cell, battery-operated system without a need for voltage boost. This capability is required to meet the latest USB Type-C 1.3 specification requirements. CMG1 contains non-volatile memory to enable customers to customise cable parameters and comes with a manufacturing tool kit that may be integrated into customers’ manufacturing flow.
