Dual IO-link transceiver shrinks solution size
Industry 4.0 is gaining traction, requiring sensors and actuators to be ever smaller, robust and able to dissipate substantially less power. Maxim Integrated Products’ announced the MAX22513 dual-driver IO-Link device transceiver with DC-DC regulator and surge protection, claiming it is the smallest and most power-efficient solution available to meet Industry 4.0 requirements.
Maxim’s highly integrated IC shrinks the solution size by 3x when compared with competing devices. Integrated surge protection eliminates the need for four TVS diodes compared to Maxim’s previous solution. All four IO pins (V 24 , C/Q, DO/DI, and GND) are reverse-voltage protected, short-circuit protected, and have ±1 kV/500Ω surge protection. The combination of surge protection and reverse polarity enables robust communication within harsh manufacturing environments.
Additional features include the transceiver’s 4x lower power dissipation, made possible by low 2Ω (typical) on-resistance drivers and a 300 mA (maximum load) DC-DC regulator with 80 percent efficiency. There is a selectable control interface, an internal high-efficiency DC-DC buck regulator and two internal linear regulators that generate 5 V and 3.3 V, supplying up to 50 mA of current. Either an SPI or I 2 C interface can be used and both full- and half-duplex SPI are supported. An internal MCLK 300 oscillator provides a clock source to a microcontroller for IO-Link communication.
Priced at $135 the MAX22513 evaluation kit includes an evaluation board, Windows-compatible software and a graphical user interface (GUI). Also available, is a fully tested MAXREFDES171# reference design for ±1.2 kV/500Ω surge protection.
The MAX22513 is currently available in a tiny WLP package (4.1 x 2.1 mm) or 28-pin TQFN-EP package (3.5 x 5.5mm) and operates over the -40°C to 125°C temperature range. It can be purchased at Maxim’s website for $3.75 each for quantities of 1,000+ FOB USA. It also is available from authorized distributors.
