ZIOL2411
General Documents
Brief Description
The ZIOL2411 is a line driver/level shifter IC with two independent HV1 I/O-channels having a wide range of configurable system features. It addresses the physical layer of sensor/actuator systems in factory automation and is especially designed to support the
communication standard IO-Link.
The output drivers are push pull stages which reach in tandem mode an RDSon of less than 3.3 Ohms at all operational temperatures.
The configuration is stored in an on-chip EEPROM and automatically loaded into the IC’s control register during power up. The IC also provides status information, such as overload and over temperature. An implemented SPI interface supports access to configuration and status registers.
The IC is produced in a powerful CMOS Mixed Signal Technology that allows supply voltages up to 40V. The EEPROM read/write functionality is guaranteed within the entire operating temperature range in combination with a low Voltage core supply of 3.3V.
