USB-C controller gains Qualcomm Quick Charge 4 approval
Quick Charge 4 supports USB Power Delivery (PD) 3.0. USB PD features programmable power supply (PPS), which provides fast, efficient charging by allowing a smartphone to communicate with the charger to intelligently select the optimal voltage and current levels. Quick Charge 4 also adds various safety enhancements and is engineered to allow for charging without overheating.
Cypress’ programmable CCG3PA controller enables firmware upgradeability to keep up with evolving standards while ensuring interoperability. The controller’s high level of integration minimizes bill-of-material costs and simplifies designs, replacing multiple discrete components with a single-chip solution.

The EZ-PD CCG3PA controller is a one-chip solution that integrates several key components—error amplifiers for constant voltage, constant current and PPS applications, a 30V 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—that are essential in a USB-C power adaptor design. Programmable overvoltage and overcurrent circuitry is included to protect systems against power overloads and other faulty operating conditions. The controller also integrates an ARM Cortex-M0 and 64 kB Flash to support firmware upgradeability.
