  • Electronic circuit device with a short circuit switch using transistors and method of testing such a device
    Patent number: 6833722
    Abstract: An electronic circuit device has contact terminal outside its package. The contact terminals are connected via the main current channels of two transistors connected in parallel between the contact terminals, so as to provide a switchable short circuit between the terminals. The device is tested by connecting two sense contacts of a resistance measuring device to the terminals and measuring the resistance between the sense contacts a first, second and third state respectively, the first and second transistor being switched on and off respectively in the first state and vice versa in the second state, both transistors being switched on in the third state. The resistance in the three states is modeled as a model resistance composed of a series resistance component in series with a first resistance component, a second resistance component and a parallel arrangement of said first and second resistance component respectively.
