1Overview

The BTS 6142D is a one channel high-side power switch (12 m

Ω) in PG-TO252-5-11

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.
