DETECTION CIRCUIT FOR DETECTING LOAD STAT, DRIVER WITH THE SAME

摘要

A load state detection circuit according to an embodiment of the present invention includes: a reference voltage generation circuit for generating a reference voltage based on a reference current; a voltage selection circuit for selecting one of a first detection voltage based on a first driving current through a load and a second detection voltage based on a second driving current through the load; and a detection circuit for generating a detection signal by comparing the reference voltage with the detection voltage selected by the voltage selection circuit. and, when the load is in a steady state, the reference voltage is higher than the detection voltage, and when the load is in a short-circuit state, the reference voltage is set lower than the detection voltage.
