摘要： In a power supply circuit, when switches are turned off, current flows from a battery power supply line through resistors, input terminals, diodes and a terminal and further from a terminal into IC. When a microcomputer operates in a low power consumption operating mode, the power supply voltage is higher than a target voltage, and a control voltage output from an operational amplifier increases, so that a transistor is turned off. At this time, a current sink circuit operates and a transistor is turned on, so that excessive current flows into the current sink circuit to suppress increase of the power supply voltage.

摘要： A communication system includes a master control unit, a plurality of slave control units, and buses connecting the master control unit and the slave control units for the asynchronous communication. When the master control unit starts the communication, each slave control unit transmits a plurality of data bits represented by whether the buses be driven to the master control unit in data transmission periods assigned to the slave control units based on a start of communication, and the master control unit drives the buses to insert a period for supplying power while data bits are being transmitted in the data transmission period. The slave control unit provides a non-driving period, which stops driving the buses, at an end of the data bit transmission period.

摘要： In a clamp circuit device, reference voltages are set up by a series circuit of an FET, a resistor and an FET. Gate potentials of FETs are set up by performing addition and subtraction of these reference voltages and a reference voltage generated by a bandgap reference circuit, respectively. The clamp circuit device is constructed by connecting together a source of the one FET with its drain connected with the power supply and a source of the other FET with its drain connected with the ground to an input terminal of a control IC unit. Thus, an input voltage is clamped to [V4+Vtp] when an excessive voltage of positive polarity is applied to an input terminal, and the input voltage is clamped to [V5−Vtn] when an excessive voltage of negative polarity is applied.

摘要： A communication system includes: a master; a plurality of slaves; and a bus for coupling among the master and the plurality of slaves in order to communicate asynchronously among the master and the plurality of slaves. The master supplies electricity to the bus in a power supply period. The master or the slave drives the bus for transmitting a one-bit data through the bus in a data transmission period. The power supply period and the data transmission period are successively performed so that data communication provided by a plurality of one-bit periods is performed among the master and the plurality of slaves. The master finely changes a communication frequency in the data communication. The master changes a drive level of the bus within a predetermined acceptable range in the data communication.
