With the rapid proliferation of smart homes, smart curtains—key components of whole-home intelligence—are moving from high-end options to standard features for the masses. However, behind this high-growth market, two major pain points continue to trouble manufacturers and users: poor multi-brand interoperability and a high rate of false voice wake-ups. These issues have become bottlenecks limiting the user experience of smart curtains. Leveraging its deep expertise in analog and mixed-signal ICs, AWINIC has launched a complete AI voice chip + full-link hardware solution for smart curtains. Centered around the AWA89501 AI voice chip, this solution redefines the interaction logic for smart curtains,totally breaking the constraints of the industry experience.
At present, the smart home ecosystem is highly fragmented. The most common complaints from users are the incompatibility of protocols across different brands and the chaotic linkage logic. Traditional smart curtains require binding to a smart speaker for voice control. If the network goes down or the devices are mismatched, voice functionality fails entirely. Meanwhile, frequent false wake-ups—triggered by everyday conversations or ambient noise—lead to unintended curtain operations, resulting in low interaction accuracy and severely diminishing user satisfaction.
To address these core industry challenges, AWINIC has launched the AWA89501 AI voice chip, creating a leading voice interaction solution for smart curtains. This chip integrates a self-developed A-NPU and a high-performance CPU, supporting pure offline voice interaction. Smart curtains can respond to local voice commands without needing a smart speaker or an internet connection, fundamentally solving the problems of multi-brand interoperability and poor adaptability. It truly delivers "install and use, cross-ecosystem compatibility."

I. On-Device AI Voice Unlocks a New Experience in Convenient Interaction
1) On-Device Voice AI Interaction
Leveraging the powerful computing capabilities of the built-in AI chip and A-NPU, the AWA89501 not only supports offline voice interaction but also enables wake-word-free conversations. Say goodbye to cumbersome commands like "Hey AI, open the curtains." Simply say "Open the curtains," "Close the curtains," or "Set curtains to half-open," and the chip accurately recognizes and executes the command. This significantly reduces false wake-up probability while achieving industry-leading response speed and recognition accuracy.
2) Deep Learning Noise Reduction
Whether in a quiet bedroom or a noisy living room, the chip accurately captures user commands, making voice interaction more natural and efficient.
3) Voiceprint Recognition
With customized voiceprint and personalized responses, your curtains will only obey your commands. The solution also supports dialects, foreign languages, and other customized options, truly enabling intelligent interaction.
II. Complete Hardware Ecosystem – A One-Stop Curtain Solution
Beyond AI voice interaction, AWINIC's smart curtain solution covers the full range of hardware: motor drivers, operational amplifiers, Hall switches, and LDOs. This one-stop solution meets all hardware requirements for smart curtains, helping manufacturers streamline R&D processes and improve product stability.
1) Motor Drivers
To meet the 1.5A and 3A current requirements of smart curtains, AWINIC offers differentiated options: the AW8637 is designed for 1.5A drive scenarios, featuring ultra-low sleep current, integrated overcurrent/overtemperature/short-circuit protection, PWM speed control, and forward/reverse control. Its small package fits the compact structure of curtain motors. The AWD8231 meets the needs of 3A high-power drive, delivering strong and stable operation, making it suitable for large, heavy curtain tracks while maintaining quietness and durability.
2) Motor Stall Detection
AWINIC recommends the AWS79032 general-purpose op-amp—a cost-effective, versatile component with low noise, wide voltage range, and high gain. It accurately captures motor operation signals, monitors stall status in real time, triggers protection mechanisms, prevents motor burnout, and extends product lifespan.
3) Curtain Position Detection for Open/Close Stop
Accurate position detection is critical for precise curtain control. The AW86502 Hall switch stands out with its ultra-low power consumption of 0.8μA, making it perfect for battery-powered smart curtains. Its omnipolar sensing design accurately detects position, achieving precise open/close/stop control. With low power consumption, it offers long battery life and greater peace of mind.
4) Power Management
For the 24V/100mA power supply requirements of smart curtains, the AWP37201 LDO is an excellent choice. It features a low quiescent current of 1.5μA, an ultra-wide input voltage range, and stable, reliable regulated output. It effectively reduces system power consumption, improves power conversion efficiency, and ensures stable power delivery to the curtain's main controller and voice module.

From core interaction to hardware support, AWINIC's smart curtain solution—centered around the AWA89501 AI voice chip—covers the entire chain of "voice interaction – motor control – signal detection – power management." It not only solves the industry pain points of poor interoperability and false wake-ups but also lowers the R&D barrier for manufacturers through high integration, cost-effectiveness, and ease of development.
Looking ahead, as whole-home intelligence continues to gain penetration, offline AI voice and full-link hardware integration will become the core competitive advantages of smart curtains. AWINIC will continue to deeply invest in the smart home chip sector, empowering end products with technological innovation. The goal is to make smart curtains more intuitive and user-friendly, helping manufacturers create more competitive smart curtain products and ushering in a new era of efficient interaction in smart homes!
