Multi-channel ignition coil driver module |
摘要 |
The multi-channel ignition coil driver module of the present invention includes a control integrated circuit and multiple high current load driver integrated circuits housed within a common 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 multiple control signal inputs to provide a corresponding multiple number of low voltage drive signals. Each of the high current load driver integrated circuits are formed of a semiconductor material manufactured in accordance with a high-voltage integrated circuit processing technology and are each responsive to a different one of the low voltage drive signals to energize a different one of a multiple number of high current loads. A current limit function is further provided in each of the multiple channels for limiting the corresponding load current to a predetermined level.
