Integrated circuit special for driving and thermostat

Abstract

The invention provides an integrated circuit special for driving. The integrated circuit comprises a driving circuit, a detection circuit, a controller, an output power tube, an integrated circuit input end, an integrated circuit output end, a power supply end and a grounding end; the input end of the drive circuit is connected with the input end of the integrated circuit, and the output end of the drive circuit is connected with the control end of the output power tube; the output end of the detection circuit is connected with the input end of the controller; the driving circuit is used for receiving the driving signal and outputting a voltage control signal; the output power tube is used for controlling on-off of a circuit between the power supply end and the output end of the integratedcircuit according to the voltage control signal; and the controller is used for outputting a corresponding fault signal according to the input of the detection circuit. The detection circuit detectsthe internal working condition of an integrated chip in real time, and outputs a fault signal when an abnormality occurs, so that the front end can perform corresponding modulation according to the fault signal, and the chip is prevented from being continuously damaged and even collapsed. The invention further provides a thermostat adopting the integrated circuit special for driving.

Description

technical field [0001] The invention relates to the field of electric drive, in particular to a drive application-specific integrated circuit and a constant temperature machine. Background technique [0002] With the development of science and technology, the application of integrated circuits has become more mature. In the constant temperature machine of water heaters, the built-in integrated circuit chip is used to control the temperature within a constant range, which greatly facilitates people's lives. [0003] However, due to the special working environment of the thermostat itself in the water heater, the control board of the existing thermostat is easily affected or even damaged, which affects the efficiency of the water heater; in addition, the control board adopts discrete components, the number of components is large, the processing is complicated, and the overall failure rate is high. .
