Mode changes are applied either by a host command, an Wake-Up event or by an under-voltage event. To trigger
a mode change by a host command or in other words by a signal change on the digital input pins EN and NSTB
all power supplies,
By setting the EN pin to logical “High” and the NSTB pin to logical “Low”, the TLE6251-3G enters the Go-To-Sleep
command and after the time t =
any mode change, also for a mode change to Sleep mode the TLE6251-3G disregards the signal on the CAN bus.
Therefore the TLE6251-3G can enter Sleep mode and remain in Sleep mode even if there is a short circuit on the
CAN bus, for example CANH shorted to
In order to recognize a remote Wake-Up, the TLE6251-3G requires a signal change from “Recessive” to
“Dominant” before the Wake-Up filter time starts (see
