MAX22513AWJ+T

Overview

The MAX22513AWJ+T is a dual-channel low-power IO-Link device transceiver featuring integrated surge protection and an internal high-efficiency DC-DC buck regulator. It supports selectable SPI or I2C control interfaces and includes two internal linear regulators generating 5V and 3.3V. The device operates with a V24 supply voltage range of 8V to 36V and logic levels from 2.5V to 5.5V. It provides configurable C/Q and DO/DI drivers with current limits ranging from 50mA to 350mA, selectable switching frequencies of 921kHz or 1.229MHz for the DC-DC converter, and ±1kV/500Ω surge protection on all IO pins. Operating temperature spans -40°C to +125°C in a WLP package.
