Abstract

See full text

Aspects of the invention are directed to a single chip igniter such that it is possible to realize a reduction in operating voltage, an increase in noise tolerance, a reduction in size, and a reduction in cost. By reducing the gate threshold voltage of a MOS transistor, and reducing the operating voltages of a current limiter circuit, an overheat detector circuit, a timer circuit, an overvoltage protection circuit, an input hysteresis circuit, and the like, it is possible to reduce the operating voltage of a single chip igniter. In some aspects of the invention, the effective gate voltage of the MOS transistor is 1V or more, and the channel length of the MOS transistor is 4 μm or less. Also, in some aspects of the invention, the thickness of a gate oxide film of the MOS transistor is 5 nm or more, 25 nm or less.
