Linear Technology’s LTC2874 quad PHY interface packs an IO-Link master, combining a power and communications interface to four remote IO-Link devices (slaves). Unique features of the LTC2874 include automatic Wake-Up Request (WURQ) generation and an output supply current-boosting capability for slave start-up. The WURQ generator produces self-timed wake-up pulses of correct polarity. The current-boosting pulse generator implements the startup current pulse requirements meeting the IO-Link v1.1.1 specification. Other features include an 8V to 30V operating range, parallelable driver outputs, and an operating temperature range from -40°C to +85°C. Available in a 5 mm × 7 mm QFN or TSSOP, pricing starts at $7.94 each in 1,000-piece quantities. For more information, visit http://www.linear.com/product/LTC2874.
