Abstract
An overcurrent protection circuit limits a monitoring target current to or below a limit current value IOCP. For example, it can operate so as to give the limit current value IOCP, when temperature Tj is lower than a threshold value Tx, a flat temperature response and, when temperature Tj is higher than the threshold value Tx, a negative temperature response. For another example, it can operate so as to set the limit current value IOCP, when temperature Tj is lower than a threshold value Tx, at a first limit current value IOCP having a flat temperature response and, when temperature Tj is higher than the threshold value Tx, at a second limit current value IOCP having a flat temperature response and lower than the first limit current value IOCP.
