摘要： An electrical power protection integrated circuit provides protection against reverse battery and overvoltage conditions that is particularly of value in automotive applications in which reverse battery and overvoltage conditions are commonplace. The electrical power protection integrated circuit device contains a reverse battery condition protection element, supplied either directly or indirectly from a battery power source, that protects against a reverse battery condition of the battery power source and an overvoltage protection element coupled to the reverse battery condition protection device that protects against an overvoltage condition of the battery power source and produces a protected power output that is isolated from both battery overvoltage and reverse battery voltage conditions. Additionally, the integrated circuit device can further produce an auxiliary protected power output that is isolated from reverse battery voltage conditions.

摘要： A catalytic converter of an engine, such as might be found in an automotive engine system, is capable of being quickly and electrically heated in order to reduce pollution emissions during critical cold start conditions. During cold start conditions, i.e. upon starting the engine, for a predetermined period of time the catalytic converter directly receives electrical power via a quick heating path connecting a catalyst power switch to the catalytic converter. Following the predetermined period of time after which the catalytic converter has been electrically heated, the catalyst power switch is connected to a junction block, such as a starter motor assembly, of the automotive engine system via a normal path.

摘要： A circuit for driving a motor used to control the HVAC blend door in an automobile is disclosed. The circuit includes an amplifier circuit, a motor, and a three state driver circuit. The driver circuit includes three NPN bipolar transistors and two PNP bipolar transistors configured such that the output of the three state driver circuit is turned off if the input is at a intermediate voltage. The output of the three state driver circuit is at a high voltage if the input is at a low voltage. Conversely, the output of the three state driver circuit is at a low voltage when the input is at a high voltage.
