Monolithic integrated circuit device.

摘要

A monolithic integrated circuit device comprises first and second output terminals (4, 5), a power switching circuit (3) which is connected across the first and second output terminals and through which electric current is supplied to an external load (10) from an external power source (8), a driving circuit (2) for generating a first drive signal (I3) to be supplied to the power switching circuit, and a third output terminal (6) in electrical connection with the driving circuit for derivation of electric energy from the driving circuit as a second drive signal (I2) to be supplied to an external circuit via the third output terminal. The monolithic integrated circuit device is capable of not only controlling power supply to an external load but also driving an external circuit which may be another power switching circuit cooperative with the power switching circuit in the present mnolithic integrated circuit device for the purpose of controlled power supply to the external load or which may be other types of electronic circuits.
