发明名称 LOAD DRIVE CONTROL DEVICE
摘要 PROBLEM TO BE SOLVED: To provide a load drive control device that can keep on driving a load as long as possible.SOLUTION: A first gate drive section 33 supplies gates of first switching elements 35, 37 with first gate driving currents indicating charging/discharge currents to/from the gates of the first switching elements 35, 37, to drive the gates of the first switching elements 35, 37. A first slope variation circuit 16increases the first gate driving currents by a unit amount when an ambient temperature of the first switching elements 35, 37 is equal to or higher than a threshold H1, and decreases the first gate driving currents by a unit amount when the ambient temperature of the first switching elements 35, 37 is equal to or lower than a threshold L1.
