ZIOL2401
Feature Sheet
Dual-Channel IO-Link HV Line Driver
with Integrated DC/DC Converter
Brief Description
Benefits
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
•
•
•
Configurable feature set
Nonvolatile storage of system configuration
Excellent electromagnetic compatibility (EMC)
performance due to adjustable output slew rate
control

•
Low RDSon of 3.3Ω in tandem mode
Programmable limitation of driver output current
DC/DC converter on-chip
†
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.
EEPROM read/write functionality within full
operating temperature range
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 inter-
face supports access to configuration and status
registers.

Application Notes
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.
