Title:
SEMICONDUCTOR DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/055908
Kind Code:
A1
Abstract:
This semiconductor device is provided with: a plurality of switching elements (11, 12) that are electrically connected to each other in parallel; a control unit (30) that outputs control signals for controlling energizing currents of the switching elements; and a temperature estimation unit (40) that estimates a temperature difference between the switching elements. When an estimated temperature difference is equal to or higher than a predetermined threshold temperature, the control unit shifts to stop mode, in which drive of a switching element at a relatively high temperature is stopped.
