Cable assembly controller with EPR supports protection for passive USB-C cables

Infineon Technologies AG introduces EZ-PD CMG2, a USB-C Electronically-Marked Cable Assembly (eMarker) controller with enhanced features. The controller is created to deliver robust USB-C PD solutions for applications such as EPR USB-C, USB4, and Thunderbolt passive cables.

The company's EZ-PD portfolio of USB-C PD controllers is the industry's most comprehensive range of USB-C power delivery solutions. The new device is a dedicated eMarker controller designed for passive non-Thunderbolt and Thunderbolt Type-C cables and supports USB-PD 3.1 and Type-C 2.1 standards. EZ-PD CMG2-based USB-C eMarker cables can handle USB4 and TBT4 data rates and up to 240W (48V/5A) of power. It provides integrated V BUS-to-CC short circuit protection up to 54V and V BUS-to-V CONN short circuit protection up to 54V. Also, it supports R A weakening to lower power consumption and integrates an oscillator and IEC ESD protection, eradicating the need for an external clock and external ESD, respectively.

The new controller has a configurable 47-byte storage space for vendor- and cable-specific configuration data and operates within a 2.7V to 5.5V V CONN supply range. The integrated high-voltage protection of up to 54V on CC, V CONN1, and V CONN2 pins safeguards against accidental shorts to the high-voltage V BUS pin on the Type-C connector, providing enhanced user safety. Also, its industrial temperature range of -40C to +85C and system-level ESD protection on CC, V CONN1, and V CONN2 pins ensure reliability and durability under challenging conditions.

The controller provides seamless compatibility with various USB-C devices and cables. It supplies a single-chip solution measuring only 3.3mm², simplifying designs and decreasing development time. Its high system reliability and compatibility result in cost-effective and easy-to-design products with a smaller board footprint for manufacturers.

The controller with EPR is available in a compact 9-ball WLCSP with a footprint of 3.3 mm² and is available to order now.
