High-voltage line driver tailored to be cost effective

ZMD AG rolls out the ZIOL2211, a line driver and level shifter IC targeted at sensor and actuator systems in the harsh environment of factory automation applications with a range of configurable system features which aids in cost saves. The IO-Link drivers are fully programmable ranging from slew rate and current settings to diagnostics features.

The ZIOL2211 is function- and pin-compatible with the ZIOL2401, ZMDI's first member of the IO-Link family, but without smart power and master functionality. This allows designers to pay only for those functions that they require.

"Since last year's introduction of the ZIOL2401, we have seen a lot of interest for IO-Link products from the market. Responding to customer demand, we developed the ZIOL2211 to complement the ZIOL2401 and thus enable designers to achieve the optimum balance of price and performance," said Bernhard Huber, ZMDI standard products business line manager.

ZMDI's existing IO-Link tools also support the ZIOL2211. Using the same IC and development tools for all serial I/O saves design time and shortens time to market. Furthermore, it allows designers to apply a proven design to a new product.

The operating temperature is -40°C to +85°C. The IC comes in a space-saving 4mm x 4mm QFN24 package. An exposed die paddle ensures optimum heat distribution. Unit prices start at Rs.127.31 ($2.85), in volumes of 1000 devices. The ZIOL2211 is scheduled for volume production in Q1 2011. Samples will be available in January 2011.

Application Kit Support
The ZIOL2401 starter and lab kit are suitable for all ZIOL2xxx ICs including the ZIOL2211. The application kit includes an evaluation board and a Windows-based configuration tool, with a USB interface between the PC and the board. Developers can easily evaluate configurations and save the results. In-system programming via SPI is also supported, allowing full customisation after manufacturing.
