CCE451024QFN

CCE4510 IO-Link Master PHY with integrated Frame Handler General Description The CCE4510 is a high-voltage interface IC with overvoltage detection as well as high temperature and high current protection, based upon a 0.35 m HV-CMOS technology. Typical applications are industrial sensors or actuators, which should support the IO-Link standard. To improve the application performance, an integrated IO-Link frame handler is provided, which automates most of the lower layer communication tasks. This reduces the microcontroller loads significantly, thus gaining more performance for other tasks, even if slower microcontrollers are used. A variety in fields of application is given by different packaging and configuration options. 1.1 Features 1.2 Schematic Two IO-Link compliant channels with 1 A peak driving current Wide voltage range
