Title:
集積回路、半導体装置
Document Type and Number:
Japanese Patent JP7318335
Kind Code:
B2
Abstract:
A semiconductor device having a switch circuit and an integrated circuit. The switch circuit includes serially-connected first and second switching devices respectively on a power supply side and a ground side thereof, and first and second free-wheeling diodes connected respectively in parallel with the first and second switching devices. The integrated circuit performs switching of the second switching device, and including a detection circuit that detects a load current flowing through a load of the switch circuit, and a drive circuit that controls magnitude of a current flowing to the gate terminal of the second switching device, to thereby charge a gate capacitance of the second switching device according to a detection result of the detection circuit, when a received drive signal is at one logic level, and turns off the second switching device when the received drive signal is at another logic level.
