Abstract
Official abstract text for this publication.
There is provided an output circuit for supplying an output current to a load coupled to an output terminal in response to an input signal. The output circuit includes an output transistor for supplying the output current to the output terminal, an output-drive circuit for driving the output transistor, a constant-current limiting circuit for generating a current control signal for limiting the output current to a predetermined current value, and a control circuit for implementing a control such that the output current is controlled on the basis of the current control signal if a voltage at the output terminal is at a predetermined voltage, or less after the input signal is supplied while the output transistor is driven by the output-drive circuit if the voltage at the output terminal is in excess of the predetermined voltage.
First claim
Opening claim text (preview).
What is claimed is: 1. An output circuit for supplying an output current to a load coupled to an output terminal in response to an input signal, said output circuit comprising: an output transistor supplying the output current to the output terminal; an output-drive circuit driving the output transistor; a current limiting circuit generating a current control signal for limiting the output current to a predetermined current value; and a control circuit implementing a control…
