The MAX22514 IO-Link transceiver integrates high voltage functionality, including one 24V line driver, an integrated DC-DC buck regulator, and 5V and 3.3V linear regulators. The MAX22514 is targeted for IO-Link devices, masters, and industrial switching sensor applications, and can be configured and monitored using a standard SPI interface.ApplicationsIO-Link and Industrial Sensor and Actuator DevicesThe MAX22514 features a SPI interface for configuration and diagnostics. A high level of integration (including two linear regulators, a DC-DC buck regulator, and integrated surge protection, combined with low power dissipation and small packages) optimizes the MAX22514 for use in many different industrial and IO-Link small sensor applications.IO-Link Master Transceivers: The MAX22514 is capable of being used in both IOLink devices and IO-Link master applications. A SPI interface is used for extended configurability and diagnostics, and the transceiver is capable of operating at the COM1, COM2, and COM3 IO-Link data rates. The MAX22514 can be configured to enable the required 5mA pull-down/pull-up current on the C/Q line and generate a wake-up pulse.

The MAX22515 low-power industrial transceiver can operate as either an IO-Link device or an IO-Link master transceiver in industrial applications. The MAX22515 features a selectable control interface (pin mode or I2C), two integrated linear regulators, and integrated surge protection for robust communication. The transceiver includes one C/Q input-output channel and one digital input (DI) channel.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 microcontroller, an I2C interface is available providing extensive configuration and diagnostics. Additionally, an integrated oscillator simplifies the clock generation for IO-Link devices.The MAX22515 features extensive integrated protection to ensure robust communication in harsh industrial environments. All IO-Link line interface pins (V24, C/Q, DI, and GND) are reverse voltage protected, short-circuit protected, hot-plug protected, and feature integrated ±1.2kV/500Ω surge protection.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 -40°C to +125°C temperature range.ApplicationsIO-Link Sensor and Actuator DevicesIndustrial SensorsIO-Link Masters

The MAX22517–MAX22519 are dual-channel digital galvanic isolators with integrated field-side supply using Maxim's proprietary process technology. The field-side power is supplied by the logic-side using an integrated isolated DC-DC converter. This approach eliminates the bulky and expensive external isolated power supply when the power demand of the field side is small. All of the devices in the family feature basic isolation with a withstand voltage rating of 3.5kVRMSfor 60s or 445VRMSof continuous operation. With a single resistor on each input, the inputs of the MAX22517–MAX22519 can withstand 1.2/50µs surge pulses up to ±2kV between inputs (common mode) or up to ±1kV between input and field ground (differential), as well as continuous shorts to 24VAC. The MAX22517–MAX22519 provide compact, reliable, and cost-efficient solutions for applications such as industrial IoT, industrial networking systems, and building automation.Both sides of the isolators are powered from a single 3.0V to 5.5V supply on the logic side, which also sets the output logic level. Both channels of the MAX22517–MAX22519 transfer data from the field side to the logic side and are always enabled. Each output is high when the corresponding input is high and low when the corresponding input is low.Devices are available with either push-pull or open-drain outputs, and output default states are either logic-high (push-pull version) or high impedance (open-drain versions). The default is the state the output assumes when either power domain of the device is undervoltage or the input is open circuit. See the Ordering Information for the part numbers associated with each option.All of the devices in the MAX22517–MAX22519 family are available in a 8-pin wide-body SOIC package with 5.5mm of creepage and clearance. The package material has a minimum comparative tracking index (CTI) of 400, which gives it a group II rating in creepage tables. All devices are rated for operation at ambient temperatures of -40°C to +125°C.ApplicationsIndustrial IoTIndustrial Networking SystemsBuilding AutomationMedical Equipment
