The report states that the automotive - grade ignition coil driver IGBT chip BLG3040 is an automotive - grade IGBT chip with an internally integrated self - clamping bidirectional Zener diode. It features a low on - state voltage, a low threshold voltage VTH, a high breakdown voltage, high self - clamping switching energy, a high junction temperature, and high ESD tolerance. It can meet the requirements of automotive ignition systems and engine control units (ECUs), providing efficient and reliable electronic ignition management solutions for different power platforms. Its comprehensive technical indicators have reached the international advanced level. From the manufacturing perspective, this product relies on the wafer - manufacturing resources within the group and the first - class domestic automotive - grade packaging and testing resources, ensuring a safe and reliable supply chain that can guarantee both production capacity and product quality. Currently, this product has been mass - introduced to several domestic and international leading Tier 1 suppliers and vehicle manufacturers, and has been successfully matched with multiple mainstream vehicle models. As of April this year, the cumulative shipment volume has exceeded 10 million units, promoting the localization process of key automotive electronic chips.

BELLING

Shanghai Belling is one of the early domestic enterprises to engage in the R & D of automotive engine ignition IGBTs, with mature and diverse overall solutions. As shown in Figure 2, in terms of pre - drivers, we can offer discrete and integrated solutions; for the core power device IGBT, Belling can provide five series for selection, suitable for various customer applications such as automotive and motorcycle engine ECUs and ignition coils.

In addition, for the engine ignition system, besides the engine ignition IGBT, we can also provide pre - drivers, comparators, reference sources, LDOs, etc., and continue to develop product series in this area.
