Abstract
Official abstract text for this publication.
A load drive device ( 100 ) includes: a first terminal (LDOF) and a second terminal (LDOR) to which a load is connected; and a driver ( 103 ) which controls the terminal voltages of the first terminal (LDOF) and the second terminal (LDOR) according to an input signal (LDIN), where the driver ( 103 ) switches, based on an operation mode switching signal (MODE), between a first operation mode for driving the load by passing an output current between the first terminal (LDOF) and the second terminal (LDOR) and a second operation mode for driving the load by passing the output current both from the first terminal (LDOF) and from the second terminal (LDOR).
First claim
Opening claim text (preview).
The invention claimed is: 1. A load drive device comprising: a first terminal and a second terminal for being connected to a first load or a second load; and a driver which controls terminal voltages of the first terminal and the second terminal according to an input signal, wherein the driver switches, based on an operation mode switching signal, between a first operation mode for driving the first load by passing an output current flowing between the first terminal and the s…
