Abstract
Provided is an internal combustion engine ignition device capable of preventing an output signal level of a drive circuit from changing sharply when shifting from a normal ignition operation mode to a protection operation mode while reducing the cost of dedicated components and the like. An internal combustion engine ignition device of the present invention includes a first differential circuit for outputting a drive signal in a first mode and a second differential circuit for outputting a drive signal in a second mode, where the first differential circuit and the second differential circuit each include a transistor and are configured such that a drive current for supplying the drive signal flows through the transistor which is common between the first mode and the second mode.
