About

EZ-PD? CCG3PA-NFET MCU subsystem

EZ-PD? CCG3PA-NFET features an Arm? Cortex? M0 CPU that is part of the 32-bit MCU subsystem, specifically optimized for low-power operation through extensive clock gating. The CPU comes equipped with a SWD interface, a 2-wire variation of JTAG, and a debug configuration that includes four breakpoint comparators and two watchpoint comparators. The device also has a flash module that includes a single bank of 64 KB flash and a flash accelerator, tightly coupled to the CPU to improve access times. Additionally, EZ-PD? CCG3PA-NFET contains a supervisory ROM that stores boot and configuration routines.

EZ-PD? CCG3PA-NFET USB PD subsystem

EZ-PD? CCG3PA features a USB PD subsystem that serves as the interface to the USB-C port. This subsystem incorporates a high-voltage regulator, dedicated OCP, OVP, and UVP comparators, current sense amplifier, and includes the necessary ESD support for Type-C interface pins. The USB PD physical layer includes a transmitter and receiver that communicate BMC-encoded data over the CC channel, utilizing the PD 3.0 standard.

EZ-PD? CCG3PA-NFET on-chip fault protection

EZ-PD? CCG3PA-NFET monitors VBUS undervoltage and overvoltage faults using internal resistor dividers which can be configured for fault thresholds and response times. The device also monitors VBUS overcurrent and short-circuit faults using internal current sense amplifiers, which are also configurable for fault thresholds and response times.?

Configurability includes choosing between auto-restart or latch-off for each fault. Overtemperature monitoring is accomplished using an external thermistor and an internal ADC. The thermistor can be connected to GPIO3. When the temperature exceeds the configured overtemperature limit, the USB-C port is disabled until the temperature drops below the set limit. All pins on EZ-PD? CCG3PA-NFET are protected against ESD, with a level of 2.2 kV HBM and 500 V CDM. The device also provides protection against accidental shorts from VBUS_C short to CC pins.

Configurable OVP, OCP, UVP, and SCP

EZ-PD? CCG3PA-NFET is designed for modern USB-C adapters and chargers: it provides a Type-C solution with Power Delivery 3.0 (PD 3.0) with support for programmable power supply (PSS) and Quick Charge 5.0 (QC 5.0). It offers broad device compatibility by also supporting legacy charging protocols. As a highly integrated USB PD controller including voltage regulation for the optocoupler flyback convertor, 24 V-tolerant regulator, VBUS-to-CC short protection, and high-voltage NFET gate driver on-chip, it significantly reduces the BOM cost and PCB area. Additionally, it supports field upgrades with free and fully USB Type-C and USB PD compliant firmware.
