Title:
半導体装置
Document Type and Number:
Japanese Patent JP6805622
Kind Code:
B2
Abstract:
A semiconductor apparatus is provided, comprising: a power semiconductor element which is connected between a first terminal on a high-potential side and a second terminal on a low-potential side; a first gate control section which controls a gate potential of the power semiconductor element according to a control signal; a discharge circuit which is discharges charges that are charged by the gate of the power semiconductor element; a second gate control section which controls the gate potential of the power semiconductor element according to a collector current of the power semiconductor element; a feedback section which feedbacks the charges to the gate of the power semiconductor element according to the collector potential of the power semiconductor element; and a current cutting off section which cuts off currents flowing from the first terminal to the gate of the power semiconductor element according to the control signal.
