Abstract

The invention relates to a current and effect stabilizing control circuit chip and a safe control electric appliance of the control circuit chip. The current and effect stabilizing control circuit chip and the safe control electric appliance adopt the technical scheme that two parallel and complementary unit circuits are adopted for forming the current and effect stabilizing control circuit chip, wherein the input end of an isolation switch arranged in each unit circuit is connected with an amplifier; the output end of the isolation switch arranged in each unit circuit is connected with a bottom supporting type safe control circuit; weak sensing signals are amplified and are then transmitted to the bottom supporting type safe control circuit to be processed by the isolation switch; the strong sensing signals can be directly sent to the bottom supporting type safe control circuit to be processed directly from the level input end; each bottom supporting type safe control circuit has the bottom supporting protection and limit exceeding safety control function; in addition, the two bottom supporting type safe control circuits are mutually locked; if the inputs of the two unit circuits are used for parallelly detecting the sensing signals and the outputs of the two unit circuits are used for serially connecting a peripheral driving executing circuit, and the capability of comprehensively preventing the fault control loss is realized, so that when the current and effect stabilizing control circuit chip is applied to safety protection and test control circuits for the temperature, the pressure, the water level, the timing and the like, the safety performance can be improved, the control loss accident can be avoided, and the purposes are wide.
