SEMICONDUCTOR DEVICE

The invention provides a semiconductor device which has a function of preheating a heating element and can realize a thermal head contributing to cost reduction of a printer. The semiconductor device is adapted for controlling energization of a heating element that performs printing. The semiconductor device includes: a strobe signal input unit receiving a printing strobe signal that causes the heating element to generate heat for printing; a preheating strobe generation circuit generating a preheating strobe signal that causes the heating element to preheat by compressing a waveform of the printing strobe signal in a time axis direction; and an output controller outputting a control signal that controls energization of the heating element based on the printing strobe signal and the preheating strobe signal. 本发明提供一种半导体装置，其具有对发热体进行预热的功能，并且可实现有助于打印机的低成本化的热敏头。所述半导体装置是控制对于进行印字的发热体的通电的半导体装置，包括：选通信号输入部，受理使所述发热体进行印字用的发热的印字选通信号；预热选通生成电路，在时间轴方向上对所述印字选通信号的波形进行压缩，由此生成使所述发热体进行预热的预热选通信号；以及输出控制部，基于所述印字选通信号及所述预热选通信号，输出控制对于所
