Dual-Channel IO-Link HV Line Driver
with Integrated DC/DC Converter
ZIOL2401
Feature Sheet
Brief Description
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 inter-
face 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.
Features
• Configurable output current limitation 56mA to
410mA per channel
• Standard cable driver/ physical layer transceiver
for IO-Link (master and device)
• Slew-rate controlled drivers
• Wide range for configurable feature set, which is
automatically loaded after power on reset
• Onboard DC/DC converter
• IO-Link-specific WURQ‡ detection
• On-chip registers and EEPROM for system
configuration and status information
• SPI interface for accessing on-chip registers and
EEPROM
• Digital interface: 3.3V output, 5V tolerant inputs
• IC temperature monitoring/diagnosis
• Over-current and over-temperature indication
Benefits
• 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
• EEPROM read/write functionality within full
operating temperature range
• Space saving 4x4mm² 24-pin QFN

ZIOL2401
Feature Sheet
Typical Applications
In field applications, the ZIOL2401
acts as a universal cable driver.
The ZIOL2401 can support IO-Link
communications as a physical-
layer transceiver (PHY) for IO-Link
devices and IO-Link masters.
Common applications:
• 24V line driver/level shifter
• IO-Link-compliant devices
• IO-Link-compliant masters
