Title:
LOAD DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/009232
Kind Code:
A1
Abstract:
Provided is a load drive device 100 comprising: a first input terminal IN1 for accepting an input of a first input current Iin1 from a power source E; a second input terminal IN2 for accepting an input of a second input current Iin2 from the power source E via an external resistor R; an output terminal OUT for outputting an output current Iout to a load Z; a current distribution unit 110 for summing the first input current Iin1 and second input current Iin2 at a prescribed distribution ratio and generating the output current Iout; and a control unit 120 for controlling the distribution ratio. As one example, it would be appropriate for the control unit 120 to control the distribution ratio according to the difference (Vx-Vy) between a first terminal voltage Vx present in the second input terminal IN2 and a second terminal voltage Vy present in the output terminal OUT.
