In 2025, humanoid robots are accelerating their transition from labs to real-world applications. As Tesla Optimus precisely assembles components on factory floors and Figure robots gracefully greet guests at hotel reception desks, "humanoid robots" have penetrated core scenarios including industry, services, and households.
Awinic Electronics, China’s leading analog and mixed-signal IC company, has launched a systematic solution tailored to the multi-modal sensing needs of humanoid robots. Covering high-precision sensing, high-efficiency power supply, and high-fidelity interaction, the solution supports the "brain, nerves, and voice" of robots.

Touch: Intelligent Sensing, Precise Feedback
Awinic’s touch controller ICs, with high reliability and sensitive response, make swiping, tapping, and other operations more aligned with human habits, infusing every interaction with a "humanized" feel.
—Multi-Channel Capacitive Sensor—
The third-generation high-sensitivity programmable capacitive touch controller AW933XX series covers 3-to-12-channel capacitive touch applications. It features 1aF capacitance detection accuracy, high sensitivity, strong anti-interference, and low dynamic power consumption, enabling precise touch detection and proximity sensing even in harsh environments. Integrated with a 32-bit ultra-low-power MCU and 20kB RAM, its firmware can be flexibly customized, empowering users to personalize settings and optimize performance based on specific application needs.

Hearing: Intelligent Sound Capture, Conversing with the World
In voice recognition, emotional companionship, or human-robot dialogue scenarios, Awinic's audio chips deliver "authentic human voice" reproduction with low latency, high fidelity, and optimized noise immunity.
—4-Channel Audio ADC—
Seamless dialogue between robots and the outside world begins with reliable voice recognition. Awinic's 4-channel audio ADC chip, the AW89403QNR, features high signal-to-noise ratio (SNR), wide dynamic range, low distortion, and low power consumption. Coupled with high-resolution gain control and a flexible I²S interface, it effectively addresses pain points such as inaudible soft speech, clipping distortion from loud recordings, and noticeable noise in far-field pickup.

—2×30W Digital Audio Amplifier—
Beyond accurate "hearing," clear "responding" is critical for robot interaction. Awinic's 2×30W digital audio amplifier features a powerful DSP audio processing algorithm, integrating virtual bass and power optimization modules. It reduces overall power consumption while delivering textured, high-quality bass. Additionally, the chip integrates battery low-temperature and low-voltage protection algorithms, ensuring stable, high-quality audio output even in low-temperature or low-battery conditions, guaranteeing reliable robot operation across various scenarios.

Energy Efficiency: Efficient Operation, Stable Endurance
As a leading analog and mixed-signal IC company, Awinic Electronics has the power management field, building a comprehensive LDO product matrix covering diverse application needs. From conventional options with 300mA to 1200mA output current, to 3A high-current versions, and a 4-channel PMIC specifically designed for Camera power supply, the portfolio fully addresses the power requirements of different modules in humanoid robots.
For compact spatial layouts, the 300mA LDOs are available not only in the classic SOT23-5L package but also in an ultra-small FOWLP 0.645×0.645 package,saving PCB placement area and perfectly fitting high-density integrated hardware designs.
The expansion into high-current and
multi-channel solutions further breaks power limitations, providing stable and
reliable power support for the coordinated operation of complex robot modules,
helping humanoid robots achieve efficient endurance and stable output across
different scenarios.
