Abstract: A load driving device including a converter, an output circuit and a timer circuit is provided. The converter receives a communication frame including a data signal through a serial communication and performs parallel conversion on the data signal to output an instruction signal instructing the output circuit to transition to a first state when the data signal includes first serial data and output an instruction signal instructing the output circuit to transition to a second state when the data signal includes second serial data. A timer circuit measures a duration time during which the converter receives the first serial data. When the measuring duration time arrives at an abnormality determination time, the timer circuit forces the output circuit to transition to the second state when the measuring duration time arrives at an abnormality determination time.

Abstract: An internal power circuit lowers a battery voltage supplied always from an external side to generate a standby power voltage. A timer continues to measure an elapse of time in a standby state, after a main relay is turned off and supply of a power voltage is interrupted. A measured time data of the timer is saved to a save register during a time measurement operation of the timer. When a stop condition for stopping the time measurement operation of the timer is satisfied, a control circuit stops the operation of the internal power circuit. When the main relay is turned on, the internal power circuit is activated to start its operation again by the control circuit so that the measured time data saved to the save register is restored to the timer.

Abstract: A sensor signal processing device includes an AD conversion section, a filter section, a timing signal generation section, and an arithmetic section. The timing signal generation section generates a signal synchronized with a crank angle of an engine based on a signal indicating the crank angle and generates a data acquisition timing signal by compensating the signal synchronized with the crank angle with a delay time of the filter. The arithmetic section acquires a plurality of sensor signals, which is transmitted from a sensor, converted from an analog signal to a digital signal by the AD conversion section, and filtered by the filter section, in a term before and after receiving the data acquisition timing signal and generates a data synchronized with the data acquisition timing signal.
