Battle rages over USB-C charging in cars
USB Type-C power delivery is penetrating the electronics market at a stunning rate, providing ten times the capability of previous USB standards. New phones such as the Asus ROG are using a single USB-C port for both power and data with a simpler connector.
and can be scaled to four ports with a single MCU. 

A software kit and GUI allows the user to assign individual port setting while providing a live monitor of voltage, power and temperature for each port. Foldback protection and fault features can be set and the fault history is displayed for reference.

The Cypress EZ-PD CCG3PA controller is sampling now with production in the first quarter of next year. This supports the USB PD 3.0 standard with programmable power supply (PPS), Qualcomm’s Quick Charge (QC) 4.0 protocol, and legacy charging standards.

“Car makers are basing their in-vehicle infotainment designs on drivers and passengers connecting their smartphones, tablets and other portable electronics, and they want to offer the convenience to quickly charge these devices without compatibility issues,” said Ajay Srikrishna, Vice President of Cypress’ Wired Connectivity Business Unit. “Our highly-integrated Automotive EZ-PD CCG3PA controller simplifies the design of reliable, in-vehicle charging ports by minimizing the need for external components. It enables fast charging while keeping pace with changes in standards.”

“The combination of our MPQ4230 USB PD-optimised, configurable Automotive Buck-Boost Converter and Cypress’ Automotive CCG3PA PD controller delivers a best-in-class user experience for in-vehicle charging ports,” said Maurice Sciammas, Senior Vice President of Sales & Marketing at Monolithic Power Systems. “Our joint reference designs give automotive systems designers a complete, easy-to-implement solution.”

The controller integrates error amplifiers for constant voltage, constant current and PPS applications, a 30 V regulator that allows direct operation from VBUS, VBUS short protection on configuration channel (CC) pins, gate drivers for high-voltage power FETs, a low side current sense amplifier, and dedicated hardware for legacy charger detection protocols plus system level electrostatic discharge (ESD) protection. Programmable overvoltage and overcurrent circuits protect against power overloads and other faulty operating conditions.

Texas Instruments, STMicroelectronics and NXP (which supplies the ASUS ROG phone) all have USB-C PD3.0 chips and
