Overview
1 Overview
The BTS 6142D is a one channel high-side power switch (12 mΩ) in P-TO-252-5-1
power package providing embedded protective functions including ReverSaveTM.
ReverSaveTM is a protection feature that causes the power transistors to switch on in
case of reverse polarity. As a result, the power dissipation is reduced.
The BTS 6142D has a current controlled input and offers a diagnostic feedback with load
current sense. The design is based on Smart SIPMOS chip on chip technology.

4.1.2 Output On-State Resistance
The on-state resistance RDS(ON) depends on the supply voltage as well as the junction
temperature Tj. Figure 6 shows these dependencies for the typical on-state resistance.
The on-state resistance in reverse polarity mode is described in Section 4.2.3.

At small load currents the resistance is artificially increased to improve current sense
accuracy. Therefore the forward voltage drop VON at small load currents is no more
proportional to the load current IL , but is controlled by an internal “two level controller”
to remain clamped to a defined value VON(NL). Figure 7 shows the dependency for a
typical device.
