Abstract:
Provided is a drive control device including: a first output node coupled to a gate node of a high-side transistor; a second output node coupled to a drive node; a first transistor provided between a first power supply node and the first output node; and a current limiting circuit and a second transistor provided in series between the first output node and the second output node, in which the current limiting circuit limits a current from the drive node toward the first output node to a predetermined value. The current limiting circuit is, for example, a transistor having a direction opposite to that of the second transistor.
