Abstract
An overcurrent protection circuit that limits a current to be monitored based on a current limit signal includes: a first transistor and a second transistor configured to form an amplifier input stage that receives input of a detection signal according to the current to be monitored; a third transistor configured to generate a current output signal according to a difference between the detection signal and a reference signal, and configured to form an amplifier output stage that inputs the current output signal as a negative feedback to the amplifier input stage; and a current mirror circuit configured to generate the current limit signal by replicating a signal based on the current output signal.
