Abstract
A load driving device is configured to reduce erroneous blocking operation in a switch. The load driving device includes: a control unit configured to output a driving signal and a non-driving signal; a first switch unit configured to switch power between a power supply unit and a load to a conductive state and a non-conductive state, and switch the power path to a conductive state when a difference between a potential of the first input line and a potential of a conducting path on the load side is greater than a predetermined value; and a second switch unit configured to connect a power supply to the first input line into a conductive state upon the control unit outputting the driving signal, and to block conduction between the power supply path and the first input line upon the control unit outputting the non-driving signal.
