Block Description and CharacteristicsInput and Power Stage
5.1.2
Failure Feedback
During failure condition the BTS3405G tries to sink a increased input current IINlim.
5.1.3
Output On-State Resistance
The on-state resistance depends on the junction temperature TJ. Figure 9 shows this dependency for the typical
on-state resistance RDS(on).
