The **DRV10983** from **Texas Instruments (TI)** is the industry’s first 24V sinusoidal sensorless brushless DC (BLDC) motor driver, offering a powerful and efficient solution for a wide range of applications. This 3A driver integrates advanced control logic, enabling reliable motor startup and optimized performance with minimal tuning time. The **180V sinusoidal sensorless technology** embedded in the DRV10983 significantly reduces noise by up to 75% compared to traditional solutions, making it ideal for use in cooling fans, ceiling fans, blowers, and small household appliances.
One of the key advantages of the DRV10983 is its **ultra-quiet operation**, achieved through a combination of 180-degree pure sinusoidal control and an advanced start-up algorithm. This results in a 75% reduction in noise levels, eliminating common issues like humming or snoring during startup. In fan applications, this design can cut down on harmonic noise by as much as 25dBA, ensuring a more pleasant user experience.
The device also offers **no-code configurability**, allowing users to adjust motor settings easily via simple register configurations without requiring complex microcontroller programming or deep motor expertise. This makes it accessible to a broader range of engineers and designers.
In addition, the DRV10983 comes with a **comprehensive protection package**, including features like overvoltage, overcurrent, overtemperature, undervoltage lockout, and five-stage rotor lock protection. These built-in safeguards not only simplify system design but also enhance overall reliability and longevity.
As a fully integrated solution, the DRV10983 includes power FETs, sensorless control logic, and optional 100mA, 3.3V, or 5V step-down converters—all on a single chip. This integration helps reduce board space, lower system costs, and accelerate development cycles.
For testing and evaluation, TI provides the **DRV10983EVM**, a low-cost evaluation board that supports 3-phase BLDC motor operation. It includes a graphical user interface (GUI), schematics, and Gerber files, making it easier for developers to get started quickly.
The DRV10983 is currently available in a compact 24-pin HTSSOP package, measuring 8mm x 6mm, making it suitable for space-constrained designs.

Wireless Router
The name of wireless router can be separated out of two keywords: wireless and routing. Understand the technical principle behind these two words, you understand the wireless router.
Wireless is also what we often call Wi-Fi. Wireless routers can convert home broadband from wired to wireless signals, and all devices can happily surf the Internet as long as they connect to their own Wi-Fi. In addition, these devices also form a wireless local area network, where local data is exchanged at high speed and is not limited by the bandwidth of home broadband.
For example, many people have smart speakers in their homes that can be used to control various smart appliances. When you say small X small X, turn on the TV, the speaker actually finds the TV through the LAN and sends instructions, and does not need to connect to the Internet; And if you let it broadcast news, you have to get data through the Internet.
The Local Area Network we talked about earlier, also known as the Intranet, is represented by the Local Area Network (LAN) on the router, so the Wi-Fi signal is also called WLAN(Wireless LAN); The Internet we want to access, also known as the extranet, is represented on the router by the WAN(Wide Area Network).
On the Intranet, the IP address of each device is different, which is called a private address. All devices on the Internet share the same public address, which is assigned by broadband operators such as China Telecom Unicom.
The router is the bridge between the Intranet and the external network. The above mentioned IP address translation, packet forwarding, is the router routing function.
In other words, the router is the hub of the home network, and the data of all the devices must be forwarded through it to access each other or reach the external network, which means that one husband is the key and ten thousand men are not open, so the comprehensive router is also called "home gateway".
