MAX22515ATG+

Overview

The MAX22515ATG+ is a low-power industrial IO-Link transceiver manufactured by Analog Devices Inc./Maxim Integrated. It operates as an IO-Link device or master transceiver with a supply voltage range of 8V to 36V and logic levels from 2.5V to 5.5V. The device features one C/Q channel and one digital input (DI) channel, supporting COM1, COM2, and COM3 data rates. It includes integrated linear regulators for 3.3V and 5V outputs, selectable driver current limits from 50mA to 270mA, and ±1.2kV/500Ω surge protection on all line interface pins. The component is housed in a 24-pin TQFN-EP package and operates within a temperature range of -40°C to +125°C.

Feature Summary

• Flexible control interface supports both I2C configuration and direct pin-mode operation for microcontroller-free applications.
• Integrated surge protection provides robust communication in harsh environments with reverse polarity and hot-plug capabilities.
• Built-in linear regulators simplify power design by providing stable 3.3V and 5V supplies directly from the V24 rail.

Applications

• IO-Link sensor and actuator devices
• Industrial sensors requiring robust interface protection
• IO-Link master implementations

Procurement Notes

Verify the specific suffix ATG+ corresponds to the 24-pin TQFN-EP package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure that ordering details match the exact part number to avoid discrepancies in package type or thermal characteristics during procurement.

Selection Notes

Select this component for designs requiring integrated surge protection and dual regulator support to minimize external BOM count. Consider the available packages based on board space constraints, choosing between WLP and TQFN options. Verify that the application environment stays within the specified operating temperature range and voltage limits for reliable performance.

Part Context

This device belongs to the MAX2251x family of IO-Link transceivers designed for industrial automation. It shares functional compatibility with the MAX22513 register set while offering enhanced integration. The series focuses on reducing system complexity through built-in protection and configurable interfaces tailored for demanding factory environments.

Replacement Considerations

The MAX22513 is noted as having a compatible register set. Verify electrical parameters and package dimensions before substitution. Other members of the MAX2251x family may offer similar functionality but require confirmation of specific feature alignment and pinout compatibility.
