Abstract
Official abstract text for this publication.
The electrical load driving apparatus includes means for alternately lowering the gate voltages of two current supply transistors connected in parallel to each other at regular time intervals, a current being supplied to an electrical load through drain-source paths of both the current supply transistors, and means for detecting wire breakage in two current supply wires in which the current supply transistors are interposed respectively at portions opposite the electrical load with respect to the current supply transistors based on the drain-source voltages of the current supply transistors.
First claim
Opening claim text (preview).
What is claimed is: 1. An electrical load driving apparatus comprising: a plurality of current supply wires connected in parallel with one another, each of the current supply wires being connected to one of a high side terminal and a low side terminal of a power source at one end thereof, and being connected to one end of an electrical load at the other end thereof, the other end of the electrical load being electrically connected with the other end of the high side terminal and t…
