A semiconductor device, and an electronic module including the semiconductor device, are described. In an example, the semiconductor device includes a first voltage side terminal arranged to be connected to an external first voltage, a second voltage side terminal arranged to be connected to an external second voltage different from the external first voltage, and a terminal which is adjacent to the first voltage side terminal and is arranged to be connected to one terminal of an external resistor. A current distributor is configured to distribute a current to a direct path to the first voltage side terminal and to a loss path to the terminal. A current driver is configured to perform current control of a current including a current between the first voltage side terminal and the second voltage side terminal.

Load drive device

Provided is a load drive device comprising: a first input terminal for accepting an input of a first input current from a power source; a second input terminal for accepting an input of a second input current from the power source via an external resistor; an output terminal for outputting an output current to a load; a current distribution unit for summing the first input current and second input current at a prescribed distribution ratio and generating the output current and a control unit for controlling the distribution ratio. As one example, it would be appropriate for the control unit to control the distribution ratio according to the difference between a first terminal voltage present in the second input terminal and a second terminal voltage present in the output terminal.

A multiple-output load driving device includes a plurality of output terminals (OUTto OUT) for outputting an output current to each of a plurality of loads (Zto Z), a control portion () configured to select either a non-DC current mode in which a non-DC current is used as the output current or a DC current mode in which a DC current is used as the output current, and a first terminal (MSET). In a case where a low-level signal is supplied to the first terminal, in the non-DC current mode, the non-DC current is outputted from all of the plurality of output terminals. In a case where a high-level signal is supplied to the first terminal, in the non-DC current mode, the DC current is outputted from a predetermined one (OUT) of the output terminals, while the non-DC current is outputted from the other output terminals (OUTto OUT).
