The TLE6251-3G can be activated from Sleep mode by a signal change on the WK pin, also called local Wake-
Up. Designed to withstand voltages up to 40V the WK pin can be directly connected to
the WK pin works bi-sensitive, meaning the Wake-Up logic on the pin WK triggers on a both signal changes, from
“High” to “Low” and from “Low” to “High” (see
