Failure Feedback
During failure condition the BTS3046SDL sinks the increased current IIN(fault).

Output On-state Resistance
The on-state resistance depends on the junction temperature TJ and on the applied input voltage. The following
Figures show this dependencies for the typical on-state resistance RDS(on).
