The diagnosis signals have to be switched on by a high signal at sense enable pin (SEN).
See
note that the diagnosis is disabled, when no signal is provided at pin SEN.
Figure 18
The SEN pin circuit is designed equally to the input pin. Please refer to
details. The resistors
IS1 and IS2 in case of reverse polarity and over voltage. Please refer to maximum ratings
on
The stand-by current of the BTS 5235L is minimized, when both input pins (IN1 and IN2)
and the sense enable pin (SEN) are on low level.
