About CQC certification

China Quality Certification Center (CQC) is a national certification body (NCB) that represents China in the Multilateral Mutual Recognition (CB) system of the International Electrotechnical Commission for Testing and Certification of Electrical Products (IECEE), as well as a national certification body that has joined the International Certification Federation (IQNet) and the International Federation of Organic Agriculture Movements (IFOAM). It is a national quality certification agency approved by the national competent authorities. Through the CQC certification, shows that the product meets the relevant quality, safety, performance and other certification requirements, in order to safeguard the interests of consumers, promote the improvement of product quality, enhance the international competitiveness of domestic enterprises.

The isolation drive product obtained CQC certification this time

Dual channel dead zone programmable isolation drive SLMi823x series

SLMi8233BDCG-DG, SLMi8235BDCG-DG, SLMi8233DDCG-DG, SLMi8235DDCG-DG

The SLMi823x product line is a dual-channel isolated gate driver that offers either 1A or 4A drive capability. The driver output voltage range is from 9V to 40V, and the input side supports a wide range of inputs from 3V to 18V, making the SLMi823x driver adaptable to a wide range of analog and digital controller interfaces. The SLMi823x complies with the UL1577 standard, in which the DFN13 package provides 2.5kVRMS isolation withstand voltage, and the SOP16W package supports 5kVRMS isolation withstand voltage. The ultra-high CMTI, extremely low transmission delay, and flexible dead zone configuration make the SLMi823x very suitable for isolated drive of MOSFET/IGBT, SiC and GaN FET.

IGBT/SiC isolation drive SLMi33x series with DESAT protection function compatible with optocoupler

SLMi330CG-DG, SLMi331CG-DG, SLMi332CG-DG, SLMi333CG-DG, SLMi334CG-DG, SLMi335CG-DG, SLMi330HCG-DG, SLMi331HCG-DG, SLMi332HCG-DGSLMi333HCG-DG, SLMi334HCG-DG, SLMi335HCG-DG

The SLMi33x product family is an advanced optocoupler compatible single channel isolated IGBT gate driver offering 1.5A, 2.5A or 4A drive capability. The SLMi33x provides a high-quality, high-performance isolated drive solution with built-in quick DESaturation (DESAT) fault detection, Miller clamping, soft turn-off, drain open fault feedback, and optional self-recovery mode. The SLMi33x meets the UL1577 standard, achieves an isolation voltage of 5kVrms and provides common-mode transient immunity (CMTI) of over 100kV/us, ensuring reliability and stability in extremely harsh operating environments.

Leading technical advantages

The isolated drive products of Suning Semiconductor are developed based on independent patented technology, featuring high performance, high cost performance and high reliability. The SLMi823x series that has passed the certification covers the OBC field of UPS, charging pile, server power supply, communication power supply and new energy vehicle powertrain system. SLMi33x is also widely used in industrial inverter, servo drive and other different motor driving fields.

[Isolation drive advantage of Suming semiconductor]
