MAX22515
IO-Link Transceiver with Integrated Protection
General Description
Benefits and Features
The MAX22515 low-power industrial transceiver can oper-
ate as either an IO-Link device or an IO-Link master trans-
ceiver in industrial applications. The MAX22515 features
● High Configurability and Integration Reduces SKU
• Operates from 8V to 36V
• Auxiliary Digital Input (DI)

grated linear regulators, and integrated surge protection
for robust communication. The transceiver includes one
C/Q input-output channel and one digital input (DI) chan-
nel.
• Selectable C/Q Driver Current: 50mA to 250mA
• Selectable C/Q Driver Slew Rate (I C Mode)

• Integrated Oscillator for IO-Link Communication
• IO-Link Wake-Up Detection and Wake-Up
• Generation
• Integrated Linear Regulators: 3.3V and 5V
• Compatible Register Set to MAX22513
• Able to Communicate at COM1, COM2, and COM3
Data Rates
The device features a flexible control interface. Pin-control
logic inputs allow for operation with switching sensors that
do not use a microcontroller. For sensors that use a mi-
2
crocontroller, an I C interface is available providing exten-
sive configuration and diagnostics. Additionally, an inte-
grated oscillator simplifies the clock generation for IO-Link
devices.
● Integrated Protection Enables Robust Systems
• ±1.2kV/500Ω Surge Protection on V , C/Q, DI, and
24
GND
The MAX22515 features extensive integrated protection
to ensure robust communication in harsh industrial en-

24
and GND) are reverse voltage protected, short-circuit pro-
tected, hot-plug protected, and feature integrated ±1.2kV/
500Ω surge protection.
• Glitch Filters for Improved Burst Resilience
• Selectable Driver Overcurrent Configuration
• -40°C to +125°C Operating Temperature Range
• Fast Demagnetization of Inductive Loads
The MAX22515 is available in a tiny WLP package
(2.5mm x 2.0mm) or a 24-pin TQFN-EP package (4mm x
4mm) and operates over the -40ºC to +125ºC temperature
range.
● Optimized for Small Designs
• Low Power Dissipation: 2Ω (typ) C/Q Driver On-
Resistance
• 1.3mA (typ) Supply Current
• Available in Two Tiny Packages:
• 20-Bump WLP (2.5mm x 2.0mm)
• 24-Pin TQFN-EP (4mm x 4mm)
Applications
● IO-Link Sensor and Actuator Devices
● Industrial Sensors
● IO-Link Masters
