The ZIOL2401 is a line driver/level shifter IC that provides two independent HV I/O channels with a wide range of configurable system features. It addresses the physical layer of sensor/actuator systems in factory automation applications and is specifically designed to support the communication standard IO-Link. The output drivers are push-pull stages, which in tandem mode reach an RDSon of less than 3.3Ω at all operational temperatures. The configuration is stored in an on-chip EEPROM and automatically loaded into the ZIOL2401's control register during power up. The ZIOL2401 also provides status information, such as overload and over-temperature conditions. An integrated SPI interface supports access to configuration and status registers. The ZIOL2401 is fabricated in a powerful CMOS mixed-signal technology that allows supply voltages up to 40V. The EEPROM read/write functionality is guaranteed within the full operating temperature range in combination with a low-voltage core supply of 3.3V.
