The Automotive EZ-PD CCG3PA controller delivers a plug-and-play user experience to automotive charging ports by providing support for the USB PD 3.0 standard with programmable power supply (PPS), Qualcomm’s Quick Charge (QC) 4.0 protocol, and legacy charging standards. As the standards continue to evolve, compliance and interoperability pose an ongoing challenge, but the programmable controller overcomes these issues with its firmware upgradeability. Additionally, the controller offers a high level of integration that minimizes bill-of-material cost and simplifies designs, replacing multiple discrete components. The Automotive EZ-PD CCG3PA controller is AEC-Q100 certified for automotive-grade performance. The controller’s programmability enables load sharing between ports, cable compensation and output power throttling based on temperature and battery voltage. The one-chip solution minimizes bill-of-material costs for USB-C power source products by integrating 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 circuitry protects systems against power overloads and other faulty operating conditions. The controller also integrates an ARM Cortex-M0 and 64KB Flash with read-while-write function for firmware upgradeability. The Automotive EZ-PD CCG3PA controller is now sampling in a 24-pin QFN (16mm2) package.
