Overview

1Overview

The BTS 6142D is a one channel high-side power switch (12 mΩ) in PG-TO252-5-11
power package providing embedded protective functions including ReverSave

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.

Load Dump is specified in ISO 7637, RI is the internal resistance of the Load Dump pulse generator

3)

Slew rate limitation can be achieved by means of using a series resistor for the small signal driver or in series
in the input path. A series resistor

Current limitation is a protection feature. Operation in current limitation is considered as “outside” normal
operating range. Protection features are not designed for continuous repetitive operation.
