Drive integrated circuit and drive control device

Abstract

A drive integrated circuit and a drive control device are provided. The drive integrated circuit comprises a serial data input pin, a power input pin, and a drive output pin. The drive integrated circuit further comprises a voltage regulator module which is connected with the power input pin and is used to convert external unstable input power into stable power supply voltage so as to supply power to multiple modules, a serial-to-parallel conversion module which is connected with the serial data input pin and is used to convert external input serial data into parallel data, a logic control module which is connected with the serial-to-parallel conversion module and is used to control the working state of a drive module, and the drive module which is connected with the logic control module at the input end and connected with the drive output pin at the output end and is used to drive a switching control device connected to the drive output pin according to the parallel data. By adopting the drive integrated circuit and the drive control device of the invention, the complexity and cost of the circuit are reduced, the number of output pins of a single chip microcomputer is reduced, resource saving is achieved, and the channel which can be drive-controlled is expanded.

Description

technical field [0001] The invention relates to a driving circuit, in particular to a driving integrated circuit and a driving control device. Background technique [0002] In the field of electrical equipment, electrical control, etc., it is often necessary to control the relay, and then control other components or equipment through the relay, and the signal to control the relay usually comes from such as computer or single-chip microcomputer (hereinafter referred to as MCU), logic circuit, control Devices, etc., are limited by the weak driving ability of the control signal, and generally need to add power drive devices, such as triodes or integrated drivers, between the relay and the MCU. There are two common relay driving methods, namely the discrete structure of common triode and the structure of integrated driver. [0003] see figure 1 , figure 1 The circuit diagram for a typical application circuit of a triode-based discrete 7-channel relay. A 7-channel relay appli...
