The invention discloses an intelligent dimming circuit for an automobile sun shield and a dimming sun shield, which are mainly characterized by comprising an MCU (Microprogrammed Control Unit) chip as a core control unit, the input and voltage stabilizing circuit is electrically connected with the MCU chip and used for stabilizing the input voltage. The voltage regulating circuit is responsible for regulating the voltage output from the MCU, and the H-bridge circuit is connected to the voltage regulating circuit and used for controlling the voltage output by the voltage regulating circuit. And the solar automatic photosensitive circuit is electrically connected with the MCU chip, so that an automatic dimming function based on illumination intensity is realized. And the manual stepless sliding touch circuit is also electrically connected with the MCU chip and provides a function of manually adjusting the transmittance. The manual and automatic dimming circuit is connected to the MCU chip and allows a user to select a manual or automatic dimming mode. Through the integration of the circuits, the manual and automatic control of the transmittance of the dimming diaphragm of the automobile sun shield is realized, the intelligent level of the sun shield is improved, and the use experience of a user is enhanced.
