8.3.1 Wake-Up Detection

The TIOL112(x) may be operated in IO-Link mode or Standard Input / Output (SIO) mode. If the device is in SIO mode and the IO-link master node wants to initiate communication with the device node, the master drives the CQ line to the opposite of its present state, and will either sink or source the current (≥ 500 mA) for the wake-up duration (typically 80 μs) depending on the CQ logic level as per the IO-Link specification. The TIOL112(x) detects this as a wake-up condition and communicates to the local microcontroller via the WAKE pin. The IO-Link communication specification requires the device node to switch to receive mode within 500 μs after receiving the wake-up signal.

For overcurrent conditions shorter or longer than a valid wake-up pulse, the WAKE pin remains in a high- impedance (inactive) state. This is illustrated in Figure 7-5.

If the driver of TIOL112(x) is disabled (EN = L), any change in CQ logic level for duration tWU1 < t < tWU2 is detected as a wake-up event and WAKE asserts low for the duration of tWUL. This is illustrated in Figure 7-6. Please refer to Table 8-4 for the summary of the conditions for Wake-Up detection.
