  In the summary meeting of the Sixth National Technical Committee for Standardization of Electrical Instruments, participating members, observers and committee representatives completed the established meeting agenda and listened to the special report of the power grid company; Peng Chuning from the Marketing Department of State Grid Corporation of China made a special report entitled "Introduction to the Power Branch of the Modern Industrial Chain of the New Power System", which brought the latest policy information of State Grid Corporation of China from 9 aspects, including the development ideas of the power branch chain, the electric energy meter sub-chain, the collection equipment sub-chain, and the metering smart laboratory.

  At this exhibition, Xinbei Technology released the AC/DC chip CN1001 that meets the 40W power requirement of IoT meters and the high-current motor driver chip CN8033!

CN1001

CN1001 is an AC/DC converter suitable for wide voltage input, high performance and ultra-low standby power consumption. The chip integrates a PWM controller and a 900V power tube, and uses high-voltage startup to achieve ultra-low standby power consumption. The chip uses PWM/PFM/PSM hybrid modulation technology to ensure optimal system efficiency within the full load range. It also integrates frequency jitter technology to simplify system EMI design. CN1001 provides extremely complete protection functions, including cycle-by-cycle overcurrent protection, CS resistor short circuit protection, VDD overvoltage protection, overload protection, output short circuit protection, feedback open circuit protection and over-temperature protection. It also has anti-strong magnetic interference function, which can ensure the stable output of the power supply system in a strong magnetic environment. The chip is widely used in smart meters, low-power instrument switching power supplies and other fields.

CN8033

  CN8033 is an H-bridge motor driver for driving reversible motors, which can drive a DC motor, a winding of a stepper motor or other loads. The CN8033 operates at a motor supply voltage of 4V to 24V, and depending on the logic control, it can provide an output current of up to 1.5A (ESOP-8) or 0.65A (SOT23-6). It has a current limiting protection of 3.5A. The CN8033 is controlled by two input pins. Two on/off inputs determine the output mode: forward, reverse, coasting or braking. When both inputs are at a low level, a very low standby circuit current can be achieved. The CN8033 is available in SOT23-6, SOP-8 or ESOP-8 packages. The chip is widely used in related fields such as smart circuit breakers, smart locks, and smart water/gas meters.

  During the conference and exhibition, many customers expressed their recognition of Xinbei's products, communicated and exchanged with our sales and marketing personnel, and also put forward many ideas and needs about meter chips. More cooperation consensus was reached through this exhibition.

On October 10, 2023, the Summary Meeting of the Sixth National Technical Committee for Standardization of Electrical Instruments and Meters and the 2023 47th International Seminar and Exhibition on Electromagnetic Measurement Technology, Standards and Products came to a successful conclusion. Thanks again to the organizers and guests. See you in the spring!
