Embodiment Construction

[0062] figure 1 A first or second input interface circuit 100 of an integrated semiconductor circuit 10 is shown, wherein the first and / or second input interface circuit 100 includes a comparator 110 with a predeterminable threshold value 112 . figure 1 The illustration in FIG. 2 only shows a segment of an integrated semiconductor circuit 10 which is generally very large-scale.

[0063] The circuit according to FIG. 1 is implemented bidirectionally, that is to say it simultaneously shows the output interface circuit 200 of the integrated semiconductor circuit 10 . Accordingly, of the integrated semiconductor circuit 10, in figure 1 The "port" shown on the right in can optionally have the function of the input terminal b and / or the function of the output terminal a. This is possible even simultaneously if necessary.

[0064] in particular, figure 1 Also shown are: a reference potential 130 , which is currently the electrical ground of the integrated semiconductor circuit 10...

Abstract

The invention relates to an integrated semiconductor circuit (10), in particular a micro-controller, for operating a transistor (301), wherein the integrated semiconductor circuit (10) has an output interface circuit (200) with an output connection (a), wherein the output connection (a) can be connected to a control connection (302) of the transistor (301), and wherein the integrated semiconductorcircuit (10) has a first input interface circuit (100) with a first input connection (b1), wherein the first input connection (b1) can be connected to a first connection (304) of the transistor (301)that is different from the control connection (302). In addition, the integrated semiconductor circuit (10) has means (310) for operating the output interface circuit (200) in accordance with an electrical signal at the first input connection (b1) of the first input interface circuit (100).

Description

technical field [0001] The invention relates to an integrated semiconductor circuit according to the preamble of claim 1 , as well as a circuit arrangement and a method according to the side claims. Background technique [0002] Electronic circuits are known on the market which can actuate power transistors, for example field effect transistors. In this context, operating situations may arise in which the load to be switched is short-circuited and the power transistor therefore draws a possibly impermissibly high current. Likewise, operating situations may arise in which the electrical connection to the load to be switched (or the load itself) is disconnected. Both of these situations are generally undesirable. Contents of the invention [0003] Disclosure of the invention [0004] The problem on which the invention is based is solved by an integrated semiconductor circuit according to claim 1 and by a circuit arrangement and a method according to the side claims. Adva...
