摘要： A Controller Area Network (CAN) node consists of a high-powered microcontroller, a low standby power regulator, a CAN bus transceiver, and a minimal CAN message buffer for storing received messages. Low power standby operation allows for the controller to power off, while the transceiver and regulator are operated in standby. The transceiver/regulator will enter run mode after the first symbol of a received CAN message is validated off the bus. As the original CAN message is received, it is buffered in the message buffer and, after stored, a status register is set to indicate the full message has been received. Once the controller has stabilized out of a wake-up mode, it retrieves the stored message and acts accordingly. The CAN message buffer is coupled to the controller by an system packet interface (SPI) interface for transmission of a controller wake-up command and retrieval of a buffered message.

摘要： A relay-less drive circuit for an inductive load preferably uses a transistor switch to couple the load to a battery, and provides a path for recirculating current around the load, which path includes a recirculating diode coupled in series with another transistor switch, such as an FET. the FET's drain and source terminals are connected to the recirculating diode, and the FET is biased, such that the FET is on when the battery is connected to the load with its nominal polarity, and the FET is off when the polarity of the battery is reversed.

摘要： A squib ignitor circuit (20,40) reduces the probability of an accidental airbag deployment to greatly increase the safety of an automobile. A squib (24,28,44) operates at a voltage significantly higher than the squib ignitor circuit (20,40) to produce heat sufficient to ignite pyrotechnic material. Thus, a short condition to the squib (24,28,44) does not produce an inadvertent airbag deployment. The squib ignitor circuit (20,40) forms a conductive path through an inductor (23,43) via a first transistor (21,41) and a second transistor (22,42). The inductor (23,43) stores energy. The inductor (23,43) produces a voltage substantially greater than the voltage powering the squib ignitor circuit (20,40) when the conductive path is broken. The inductor (23,43) releases the stored energy to the squib (24,28,44) generating heat. A sequence (more than one time) of storing energy and releasing energy by the inductor (23,43) is required to generate heat sufficient to ignite pyrotechnic material by the squib (24,28,44).

摘要： A voltage conversion circuit is responsive to a pulse-width modulated control signal for alternately enabling the gates of first and second field effect transistors which converts a high voltage input signal to a low voltage output signal. A first state of the control signal passes the high voltage input signal through the first transistor to charge a filter, while a second state of the control signal blocks the high voltage input signal from the filter. The second state of the control signal also sources current through the second transistor to the filter to rectify the low voltage output signal. The first and second transistors have non-overlapping conduction periods.
