Maxim's 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.
The DC-DC buck regulator supplies up to 300 mA of load current and has an adjustable output voltage from 2.5 V to 12 V. Internal linear regulators generate 5 V and 3.3 V, supplying up to 50 mA of current.
The MAX22513 can be controlled using SPI or I²C 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.
The MAX22513 features extensive integrated protection to ensure robust communication in harsh industrial environments. All four IO pins (V24, C/Q, DO/DI, and GND), are reverse voltage protected, short circuit protected, and feature integrated ±1 kV/500 Ω surge protection.
The MAX22513 is available in a tiny WLP package (4.1 mm x 2.1 mm) or 28-pin TQFN-EP package (3.5 mm x 5.5 mm) and operates over a -40°C to +125°C temperature range.
