Document Type and Number:
WIPO Patent Application WO/2002/059478
Kind Code:
A1
Abstract:
A control circuit (130) carries out ON/OFF control of the primary current in an ignition coil in response to an input ignition control signal. The control circuit (130) and an insulated-gate bipolar power transistor (IGBT) (110) are integrated on a monolithic silicon substrate.
