Description

This reference design demonstrates the ability to have a high-density: IO-Link transceiver module: digital output (DO) (1) channel: and a DC-DC buck converter. With the DC-DC this module can power a wide array of external devices: such as microcontrollers (MCUs): sensors: displays: and more. IO-Link and DO communication channels offer a wide range of flexibility for different applications. This reference design will fit applications that require a combination of sensors: such as a flow meters: level sensors: motion sensors: light sensors: or ultrasonic sensors. The TIOL111 and TIOS101 have high tolerances to ESD as outlined in IEC 61000-4-4 and IEC 61000-4-5 (500 Ω): allowing them to be used in industrial settings where there is a potential for high amounts of ESD. With the addition of transient voltage suppression (TVS) diodes: the level of ESD protection can be raised substantially. This reference design only implements the physical layer of IO-Link.
