Abstract

The invention relates to an integrated circuit with a programmable control power device, which comprises a serial communication unit, an erasable register unit, a command decoder, an algorithm execution unit and an expanding unit. The algorithm execution unit comprises a P algorithm module, an I algorithm module, a D algorithm module and the like which are independent from each other; and the expanding unit comprises an eight-path PWM output unit which outputs control signals to a controlled power device, and a device protection unit. The integrated circuit integrates the algorithms module inside so that the systematic programmability is strong and the algorithms can be established quickly, intuitively and efficiently to achieve functions; besides, because the integrated circuit is a hardware structure and all the modules are independent from each other, the real-time processing speed of the modules is fast and the controlled power device is protected comprehensively.

Description

technical field [0001] The invention relates to an integrated circuit, in particular to an integrated circuit for controlling power devices. Background of the invention [0002] At present, the control of power devices is mainly realized by integrated circuits, single-chip microcomputers and DSP. Integrated circuits are currently mainly used for ordinary switching power supplies and motor control. Although this type of integrated circuit has the advantage of low cost, it also has the disadvantage of single function and cannot meet the special requirements of different users; although the use of single-chip and DSP is relatively flexible, it can be programmed It meets the requirements of different users, but the overall processing speed is relatively slow. It can meet the requirements for applications with low switching frequency or low data processing volume, but for applications with high switching frequency or large data processing volume. The application is a bit weak. ...
