Next generation transmission solutions
· As a next-generation power technology, wireless charging is a rapidly growing application in the electrical industry. STMicroelectronics introduces a WPC-based Qi-based wireless charging solution based on advanced digital power control ICs with integrated microprocessor core and power control The peripheral circuit, which uses only one chip to meet all the requirements of the Qi specification, helps to reduce material billing costs. The screen shows the voltage and frequency status of the entire power supply system from the power transmission board to the powered device.
· As mobile device USB charging is widely used, a new charging specification called USB Power Transfer (USB PD) has emerged in the market. The specification allows users to charge more power-hungry appliances via USB, such as laptops and monitors. STMicroelectronics' USB PD-compatible power control chip enables USB to be used to transfer power between boards. The USB PD protocol is used to view the power supply and power-supply power supply categories to provide the best power capacity for the target device (maximum 100W). ).
· SiC (silicon carbide) has attracted widespread attention in the industry. As a next-generation semiconductor material, this new technology can significantly reduce the power loss of power semiconductor devices. Power MOSFETs using silicon carbide technology can significantly increase the energy efficiency of power supplies such as switching power supplies and DC-DC converters. ST's first 1200V silicon carbide power MOSFET has the industry's highest rated operating temperature of 200°C. Because of the extremely low increase in on-state resistance at high temperatures, new devices help improve system energy efficiency and reliability.
Smart home solutions
· Sensor nodes installed in various locations indoors and outdoors enable remote monitoring of the surrounding environment of the house. As a leader in sensors and IoT technology, STMicroelectronics has released a laptop-based environment remote monitoring demonstration with sensor nodes built-in temperature sensors, humidity sensors, low-power microcontrollers, and wireless transceiver chips below 1 GHz. An ultra-low power DC-DC converter chip compatible with solar cells or thermoelectric generators. Remote environmental monitoring can help improve the efficiency of home appliances such as air conditioners and broaden the range of applications for smart homes and smart offices.
· STMicroelectronics has released a remote control of indoor and outdoor LED lighting through the network. ST's indoor lighting solutions integrate PFC controller chips, LED controller chips, 8-bit microcontrollers and Bluetooth communication chips for notebook-based indoor lighting brightness control. ST's outdoor lighting solution integrates a digital power controller chip, a 32-bit microcontroller, a wireless transceiver chip below 1 GHz, and controls brightness through a 32-bit microcontroller development board (gateway) with an onboard LCD touch screen . STMicroelectronics offers a complete product portfolio for remote control LED lighting applications, including all key components.
Wearable technology solutions
· The wearable device market has experienced rapid growth in recent years, and STMicroelectronics has introduced a transponder platform based on a 32-bit ARM® Cortex®-M microcontroller that integrates multiple sensors (motion sensors, air pressure sensors, temperature sensors, Humidity sensors, proximity sensors and MEMS microphones use ST's advanced technology and signal processing and data detection technologies.
· STMicroelectronics has also released a watch-type optical heart rate monitoring solution for smart watches and fitness equipment. The solution uses ultra-low power 32-bit microcontrollers, accelerometers, Bluetooth communication chips and wearable device chips. On the back of the wearable device shown is a wrist-facing LED light that uses the LED as a light source to measure the light reflected by the user's blood flow using a photodiode and a microcontroller to determine the heart rate. The communication chip sends the heart rate data to a laptop or smartphone and displays it on the display for the user to view.
In addition, STMicroelectronics will introduce a high-precision 3D printer motor control solution with built-in 32-bit microcontroller and multiple motor drivers, digital power solutions for AC adapters and switching power supplies, and faster development. And e-Design development kits that reduce development costs.
