ABSTRACT:
The ignition coil driver module of the present invention includes a control integrated circuit and a high current load driver integrated circuit housed within a common package such as a TO-247 or TO-264 package. The control integrated circuit is formed of a semiconductor material manufactured in accordance with a standard low-voltage integrated circuit processing technology and is responsive to a control signal input to provide a low voltage drive signal. The high current load driver integrated circuit is formed of a semiconductor material manufactured in accordance with a high-voltage integrated circuit processing technology and is responsive to the low voltage drive signal to energize the high current load. A current limit function is further provided for limiting the load current to a predetermined level.
