The diagnosis signals have to be switched on by a high signal at sense enable pin (SEN).

Please note that the diagnosis is disabled, when no signal is provided at pin SEN.

The stand-by current of the BTS 5234G is minimized, when both input pins (IN1 and IN2)
and the sense enable pin (SEN) are on low level.
