Infineon launches EPR electronically marked cable assembly controller to provide overvoltage protection up to 54V for USB-C passive cables

【Lansheng Technology News】The USB-C PD controller in Infineon’s EZ-PD product series is the industry’s most comprehensive USB-C power supply solution. EZ-PD CMG2 is an EMCA dedicated controller designed for passive non-Thunderbolt cables and Thunderbolt Type-C cables, supporting USB-PD 3.1 and Type-C 2.1 standards.

The EZ-PD CMG2-based USB-C EMCA cable supports the data transfer rates of USB4 and TBT4 interfaces and charging power up to 240 W (48 V/5 A). EZ-PD CMG2 integrates functions such as VBUS to CC short circuit protection (short circuit overvoltage protection up to 54 V) and VBUS to VCONN short circuit protection (short circuit overvoltage protection up to 54 V). In addition, the controller has attenuated RA to reduce power consumption and integrates oscillator and IEC ESD (electrostatic discharge) protection, so it can operate without external clock and external ESD.

The new controller from Infineon offers configurable 47 bytes of memory space for storing vendor- and cable-specific configuration data and is capable of operating over a VCONN supply voltage range of 2.7 V to 5.5 V. Among them, the CC, VCONN1 and VCONN2 pins support high-voltage protection up to 54 V, which can prevent accidental short circuit of the high-voltage VBUS pin on the Type-C connector, thus improving the safety of use.

In addition, the controller's rated operating temperature range is the standard industrial temperature range of -40°C to +85°C, and the CC, VCONN1 and VCONN2 pins have system-level ESD protection designs to ensure that the device works in severe environments. reliability and durability.

The EZ-PD CMG2 controller is seamlessly compatible with a variety of USB-C devices and cables. It offers a single-chip solution measuring just 3.3 mm², simplifying design and reducing development time. Its outstanding system reliability and compatibility enable manufacturers to introduce cost-effective products with simple designs and smaller footprints.
