ABSTRACT:
An ignition circuit is formed in one chip comprising an insulated gate bipolar transistor for controlling the flow of a primary current, a current limiting circuit for limiting the current flowing into the transistor, and a thermal shut-off circuit capable of forcibly shutting off the primary current in case of trouble. In the ignition circuit, a power supply GND terminal and an ignition control signal positive terminal are divided.
