最近,功率 MOSFET 器件正受到人们的注目。从器件的特性来看,功率 MOSFET 与以往的双极型器件有所不同。本文以文字处理机(HW—900F)为例对功率 MOSFET 打印机驱动电路的应用予以说明。文字处理机结构文字处理机由图1所示的几个部分构成,通过键盘输入,从相当于字典的 ROM 中找出相应的词或者词组,再写入能保存文章内容的 RAM 中,并从字符生成 ROM 读取显示用的 Recently, power MOSFET devices are attracting attention. From the characteristics of the device point of view, the power MOSFET and bipolar devices in the past are different. This text processor (HW-900F) as an example of the power MOSFET printer driver circuit is described. Word processor structure Word processor consists of several parts shown in Figure 1, through the keyboard input, from the equivalent of the dictionary ROM to find out the corresponding words or phrases, and then can write the contents of the article to save the RAM, and from Character generation ROM read display
