Abstract:
An igniter semiconductor device and an igniter system can prevent the influence of a voltage drop of an ON signal voltage input to an input terminal and the influence of a surge voltage, allow a switching element to operate reliably, and prevent an ignition failure. The igniter semiconductor device includes an external terminal including at least an input terminal, an output terminal electrically connected to an ignition coil, a ground terminal, and a power supply terminal electrically connected to a regulated power supply wire outside the igniter semiconductor device. The ignited semiconductor device further includes a switching element for controlling current flowing in the ignition coil, and a driving circuit that receives power through the power supply terminal and drives the switching element based on a signal input from the input terminal.
