Description
The RH4Z2501 is a line driver / level shifter IC for IO-link communication with integrated protection. It addresses the IO-Link device physical layer for sensors and actuator systems. Furthermore, the IC can also be used as single channel master. For device configuration and status reading, an OWI communication interface is available. The output drivers allow push-pull operation, with a maximum RDSon of less than 2.5Ω for all operational temperatures. The RH4Z2501 is fabricated in a powerful CMOS mixed-signal technology that allows short supply voltage peaks up to 60V.
