INTRODUCTION
The MC33094 is designed for engine compartment use in
12V automotive ignition applications to provide high
performance control of the ignition coil when used with an
appropriate Motorola Power Darlington Transistor. Engine
control systems utilizing these devices for ignition coil control
exhibit superior fuel efficiency and lower exhaust emissions
over predecessor systems. The device is designed for single
input control from a Hall sensor to determine crankshaft
position.
The device, a bipolar linear integrated circuit, is built using
high–density Integrated–Injection Logic (IIL) processing
incorporating high current–gain PNP and NPN transistors. All
module inputs are transient voltage protected through the
use of resistors, capacitors, and/or zener diodes working in
conjunction with internal protection elements. These
elements provide protection of critical circuitry from externally
induced high–voltage transients which may degrade the
devices operational performance. At the module level, it is
recommended the VCC pin of the device be transient
decoupled using an external resistor and capacitor to work in
conjunction with the on–chip internal zener string to provide
robust module protection of the device power pin. The D
(Distributor input) input of module should be protected from
transients through the use of an external resistor and zener
diode. The Start input of the module should be decoupled
through the use of two resistors and a capacitor to work in
conjunction with the on–chip internal clamp (Figure 13).
The output of the device incorporates a high current–gain
PNP designed to drive an external power Darlington
transistor to provide control of the ignition coil. The output
drive is carefully synchronized with the output from the
distributor. The charging and discharging of three capacitors,
external to the device, provide timing signals which program
the dwell and charge time control of the ignition coil over a
wide RPM range.
The timing and charge/discharge rates of the three
external capacitors are accurately controlled by internal
circuitry acted upon by sensor and distributor signal detection
of the device.
A feedback path from the emitter of the external power
Darlington transistor to the device provide monitoring of the
