TLE 4729 G
Only in the case of a short circuit to GND, the most probably kind of a short circuit in
automotive applications, the malfunction is signaled dominant (see d) in logic table) by
a separate error flag. Simultaneously the output current is disabled after 30 µs to prevent
disturbances.
A phase change-over or putting both current control inputs of the affected bridge on low
potential resets the error flipflop. Being a separate flipflop for every bridge, the error can
be located in easy way.
