A versatile 250/300-V IC process for analog and switching applications

A true analog high-voltage IC process and related devices are described. The process is based on bipolar low-voltage devices to which have been added 300-V lateral n-MOS and p-MOS transistors with source-follower capability. The present process version includes 250-V vertical DMOS transistors for compact switching of moderate power, whereas 5/20-V CMOS is available for control. Application examples are an 8-MHz video output amplifier and a 20-W full-bridge power switch.
