MAX22513
Surge Protected Dual Driver IO-Link
Device Transceiver with DC-DC
General Description
Benefits and Features
● High Configurability and Integration Reduces SKU
The MAX22513 dual-channel low power IO-Link device
transceiver features a selectable control interface, internal
high-efficiency DC-DC buck regulator, two internal linear
regulators, and integrated surge protection for robust
communication. The device features low-on resistance
drivers (C/Q and DO/DI), selectable driver current limits,
and overcurrent protection to reduce power dissipation in
small sensor applications.
• Configurable C/Q and DO/DI Drivers
• PNP, NPN, and Push-Pull Modes
• Individual Slew Rate Control for Drivers
• Selectable Driver Current Limit: 50mA to 250mA
2
• Control and Monitoring with I C or SPI
• Half- and Full-Duplex SPI Modes
• Integrated High-Efficiency DC-DC Buck Regulator
• Selectable Switching Frequency
The DC-DC buck regulator supplies up to 300mA load
current and has an adjustable output voltage (from 2.5V
to 12V). Internal linear regulators generate 5V and 3.3V,
supplying up to 50mA of current.
• 921kHz (typ) or 1.229MHz (typ)
• 300mA (max) Load
• Output Voltage from 2.5V to 12V
• Internal 5V and 3.3V Linear Regulators
• Accurate Oscillator for IO-Link Communication

The MAX22513 can be controlled using SPI or I C
interfaces, providing flexibility for microcontrollers, and
extensive control and diagnostic features. Both full-
and half-duplex SPI are supported. The internal MCLK
oscillator provides a clock source to a microcontroller for
IO-Link communication.
● Integrated Protection Enables Robust Systems
• Integrated ±1kV/500Ω Surge Protection
• Glitch Filters for Improved Burst Resilience
• Selectable Overcurrent Configuration
• Hot-Plug and Reverse Polarity Protection
• -40°C to +125°C Operating Temperature Range
The MAX22513 features extensive integrated protection
to ensure robust communication in harsh industrial
● Optimized for Small Sensor Designs
• Low Power Dissipation:
environments.All four IO pins (V , C/Q, DO/DI, and GND),
24
are reverse voltage protected, short circuit protected, and
feature integrated ±1kV/500Ω surge protection.
• 2Ω (typ) On-Resistance for C/Q and DO/DI
Drivers
The MAX22513 is available in a tiny WLP package
(4.1mm x 2.1mm) or 28-pin TQFN-EP package (3.5mm
x 5.5mm) and operates over the -40°C to +125°C
temperature range.
• Available in Two Tiny Packages:
• 28-Pin TQFN-EP (3.5mm x 5.5mm)
• WLP (4.1mm x 2.1mm)
