C. Diagnostic Output and Over-temperature
Protection
The diagnostic signal indicates the primary coil
current level to the micro-controller. The diagnostic
output goes high when the coil current exceeds
4.5A, and low when it exceeds 5.8A, as shown in
Figure 3. This information allows the micro-controller
to govern the dwell angle and to detect the coil

saturation. In addition information on the chip
temperature is supplied. If the temperature of the die
exceeds 150
the collector current exceeds 2.5A, Figure 7, allowing
the micro-controller to start taking suitable action. It
returns to normal working mode when the chip
temperature falls to 130
