Jinxin Electronics launches intelligent small home appliance control chip solution
With the rapid progress of technology and the substantial improvement of living standards, the performance of home appliances has been upgraded, and it is increasingly convenient, intelligent, miniaturized and energy-saving. Colorful, good-looking, and high-performance small household appliances have also quietly blossomed. Household usage scenarios make small household appliances have high requirements for motor miniaturization, high efficiency, low noise, high control accuracy and long life, and are also very sensitive to the cost of motors. As a result, DC brushless motors have become the preferred solution for small household appliance applications.
Compared with previous small home appliances, smart small home appliances are more concerned about improving product energy efficiency and operation convenience to meet consumer needs, which also puts forward higher requirements for the algorithm and resources of its main control chip. As one of the cores of intelligent small household appliance motor control, DSP chip has the characteristics of high integration, low power consumption and strong real-time performance, and can process various external information inputs at the same time in small household appliances, and command each functional unit to operate intelligently and efficiently to achieve the effect of human-computer interaction. Jinxin Electronics provides a variety of main control chip application solutions for small household appliances, which can meet the diverse needs of customers.
As the main control chip of high-speed hair dryers, the high-performance 16-bit DSP ADP16F03 of Jinxin Electronics has a maximum frequency of up to 100MHz, built-in rich functional modules, and has calculation functions such as division, square square, anyway tangent, park transformation, 32-bit multiplication and shift, and has strong anti-interference ability. The chip also integrates rich peripheral resources such as 4 op amps, 3 comparators, and 3-way capture, which can more accurately and efficiently implement the sensorless FOC core algorithm and realize the smooth operation of the motor.
