Title:
IGNITION DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2019/146393
Kind Code:
A1
Abstract:
Provided is an ignition device for an internal combustion engine, the device being capable of preventing an output signal level of a drive circuit from sharply changing when switching from a normal ignition operation mode to a protective operation mode, while also suppressing the costs of exclusive components, etc. This ignition device for an internal combustion engine is provided with a first differential circuit that outputs a drive signal when in a first mode, and a second differential circuit that outputs a drive signal when in a second mode. The first differential circuit and the second differential circuit are each provided with a transistor, and are configured so that a driving current that supplies the drive signal flows through the transistor that is common between the first mode and the second mode.
