Shuming Semiconductor CQC product certification
1. Two-channel dead zone programmable isolation driver SLMi823x series
[SLMi8233BDCG-DG, SLMi8235BDCG-DG, SLMi8233DDCG-DG, SLMi8235DDCG-DG]
The SLMi823x product series are dual-channel isolated gate drivers that can provide 1A or 4A drive capability. The driver output voltage range supports from 9V to 40V, and the input side supports a wide range of inputs from 3V to 18V, making the SLMi823x driver adaptable to various analog and digital controller interfaces. SLMi823x complies with UL1577 standard, among which DFN13 package can provide 2.5kVRMS isolation withstand voltage, and SOP16W package can support 5kVRMS isolation withstand voltage. Ultra-high CMTI, extremely low transmission delay, and flexible dead-zone configuration make SLMi823x very suitable for isolated drive of MOSFET/IGBT, SiC and GaN field effect transistors.
2. Compatible with IGBT/SiC isolation driver SLMi33x series of optocoupler with DESAT protection function
[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 series is an advanced optocoupler compatible single-channel isolated IGBT gate driver that can provide 1.5A, 2.5A or 4A drive capability. SLMi33x has built-in fast desaturation (DESAT) fault detection function, Miller clamp function, soft shutdown function, open-drain fault feedback and selectable self-recovery mode, providing high-quality, high-performance isolated drive solutions for the system.
SLMi33x meets the UL1577 standard, achieves an isolation voltage of 5kVrms, and has a common mode transient immunity (CMTI) of more than 100kV/us, ensuring reliability and stability in extremely harsh working environments.
Leading technical advantage
Shuming Semiconductor’s isolation drive products are based on independent patented technology research and development, with high performance, cost-effective, and high reliability product characteristics.
