How resistant is the Superchip to interference?

Superchip's anti-jamming capability is excellent overall, and the following are its specific reflections in different types of chips:

LED Display Line Scan Driver

• Innovative connection structure: Superchip's December 2024 patented common-anode LED display line scan driver chip adopts an innovative connection structure, which reduces signal interference, improves the brightness and color reproduction of the screen, and allows the LED display to display images stably in complex electromagnetic environments, and reduces flickering and color distortion caused by interference.
• Optimized drive design: Compared with the traditional common cathode drive, the common anode drive simplifies the circuit structure and improves image stability while reducing interference, allowing the LED display to achieve higher brightness and more vivid color performance at lower voltages, and thus better resist electromagnetic interference from the power supply and other electronic components.

Power Management Chip

• Dithering: Superchip's FM2842 quasi-resonant flyback controller chip, for example, has a dithering function that effectively reduces electromagnetic interference. By constantly changing the switching frequency, the electromagnetic energy generated by the chip is dispersed over a wider frequency band, avoiding the concentration of energy at a specific frequency and causing interference to other electronic devices, and also reducing the possibility of being subjected to external interference of the same frequency.
• Multiple protection mechanisms: the chip also has over-power, over-voltage, short-circuit and other multiple protection mechanisms, when the chip detects abnormal voltage, current or power changes, it can quickly take protective measures to prevent the chip from being damaged due to interference, ensuring the stability and reliability of the power system.

Microwave radar sensor SOC chip

• Superchip's FM5821 microwave radar sensor SOC chip operates in the 5.8G ISM frequency band, which is relatively pure and subject to less external interference. At the same time, the chip applies Doppler radar algorithm to recognize object motion, which can effectively distinguish between target and interference signals, improving the accuracy and reliability of object motion detection.
• Built-in LDO: The chip has a built-in LDO (low dropout linear regulator), which can effectively reduce the interference from external power supply. the LDO can provide stable power supply for the chip, reduce the impact of power fluctuation on the chip's performance, and ensure that the chip can work stably under all kinds of power supply conditions, which can enhance the chip's ability to resist interference in the complex power supply environment.
