本文介绍了单片式带地址译码磁心驱动器的试制情况。为了提高电路的性能,我们在线路设计、版面设计和工艺设计方面都采取了一些措施。由于采用了解质隔离工艺,使得输出中功率管的饱和压降可以做得很小(无需进行深磷扩散)。 This article describes the trial version of a single-chip addressable core driver. In order to improve the performance of the circuit, we have taken some measures in circuit design, layout design and process design. As a result of the solution of the quality of the isolation process, making the output of the power tube saturation voltage drop can be done very small (no need for deep phosphorus diffusion).
