Single Channel IO-Link HV Line Driver with Integrated DC/DC Converter

The ZIOL2201 is a line driver/level shifter IC that provides an HV I/O channel with a wide range of configurable system features. It addresses the physical layer of sensor/actuator systems in factory automation applications, and it is specifically designed to support the communication standard IO-Link. The output driver is a push-pull stage that reaches an RDSon of less than 6.6Ω at all operational temperatures. The configuration is stored in an on-chip EEPROM and automatically loaded into the ZIOL2201's control register during power-up. The ZIOL2201 also provides status information, such as overload and over-temperature. An integrated SPI interface supports access to configuration and status registers. The ZIOL2201 is fabricated in a powerful CMOS mixed-signal technology allowing supply voltages up to 40V. EEPROM read/write functionality is guaranteed within the entire operating temperature range in combination with a low-voltage 3.3V core supply.
