Abstract

The invention provides a semiconductor power switch device and an electronic device and relates to the technical field of microelectronics. The semiconductor power switch device comprises a semiconductor power switch circuit, a level conversion circuit for supplying a control signal to the semiconductor power switch circuit, and a power supply circuit for supplying electric energy to the level conversion circuit. A high potential end of the semiconductor power switch circuit is connected with a high potential pin and a third input end of the power supply circuit. A control end is connected with a first output end of the level conversion circuit. A low potential end is connected with a grounding pin and a second output end of the level conversion circuit. A first input end of the level conversion circuit is connected with a control pin. A second input end is connected with a signal ground pin and the second output end. A power supply end is connected with a third output end of the power supply circuit. Through setting of the level conversion circuit, the stable control signal can be supplied to the semiconductor power switch circuit, thereby solving the problem that in the prior art, the semiconductor power switch circuit is liable to generate malfunction.

Description

technical field [0001] The invention relates to the technical field of microelectronics, in particular to a semiconductor power switching device and electronic equipment. Background technique [0002] The switching tube composed of semiconductor power devices is the core of modern power converters. The stability and reliability of semiconductor power devices have a crucial impact on the reliability of the entire power converter system, so improve the stability and reliability of semiconductor devices have important meaning. [0003] The inventors have found through research that, in the existing semiconductor power devices, the control signal is likely to fluctuate under the influence of external or internal interference factors, which leads to misoperation of the semiconductor power switch. Contents of the invention [0004] In view of this, the purpose of the present invention is to provide a semiconductor power switching device and electronic equipment to solve the pro...
