1Overview

The BTS 5230GS is a dual channel high-side power switch (two times 140 m

Ω) in

P-DSO-14-18 package providing embedded protective functions.

The Enhanced IntelliSense pins IS1 and IS2 provide a sophisticated diagnostic feedback

signal including current sense function and open load in off state. The diagnosis signals

can be switched on and off by the sense enable pin SEN.

An integrated ground resistor as well as integrated resistors at each input pin (IN1, IN2,

SEN) reduce external components to a minimum.

The power transistor is built by a N-channel vertical power MOSFET with charge pump.

The inputs are ground referenced CMOS compatible. The device is monolithically

integrated in Smart SIPMOS technology.
