APPLICATION NOTE
to the most negative supply. The selection of an n-
type substrate as the starting point allows complete
compatibility between vertical NPN and IC fabrication
steps. As in standard power NPN, the thickness and
resistivity of the first epi layer set the BV
ruggedness of the high voltage device, whereas the
second epi growth defines the characteristics of the
low voltage device. The choice of a suitable value
for the substrate thickness and resistivity, together
with an appropriate edge termination, allows the
structure to handle any blocking voltage up to 1.2kV.

FUNCTIONAL DESCRIPTION
The VB027 is a solid state integrated ignition driver
circuit designed to drive a high-energy coil under the
direct control of a micro-controller. It is constructed
utilising VIPower M1 technology, the Vertical
Intelligent Power technology from SGS-THOMSON
Microelectronics. The typical system configuration
and block diagram of the device are shown in figure 2.
