Abstract
A load abnormality detecting system and method for detecting the burnout and short circuit of a load are provided. A voltage generator () generates a specified voltage Vs in accordance with a load current IL. A judging device () compares a signal corresponding to this voltage (Vs) with a specified reference value (TT) to judge whether a load () has any abnormality. A selector () causes the burnout reference value (T) to be inputted to the judging device () and controls the voltage generator () to use a first resistance value when checking the burnout of the load () while causing the short-circuit reference value (T) to be inputted to the judging device () and controlling the voltage generator () to use a second resistance value when checking the short circuit of the load ().
