Core Viewpoint - The article focuses on the disassembly and analysis of the headlight driver module of the Xiaomi SU7, highlighting its advanced technology and components that differentiate it from traditional fuel vehicles [5][16]. Summary by Sections Overview of the Headlight Driver Module - The headlight driver module is described as the "brain" of the lighting system, essential for high-precision light control, dynamic lighting, communication, and energy management in automotive applications [5]. Disassembly Insights - The disassembly process of the SU7 headlight driver module was challenging due to the extensive use of adhesive between the bottom shell and the metal front cover, requiring significant effort to extract the driver board [7]. Component Analysis - The core controller is an Infineon automotive-grade MCU (CYT2B75CADQ0AZEGS) based on the Arm Cortex-M4 architecture, responsible for lighting logic operations, PWM waveform generation, fault diagnosis, and communication protocol stack execution [11]. - Two CAN bus controllers from NXP are included for communication redundancy, with one supporting CAN FD for high bandwidth lighting command transmission [11]. - The module features a linear voltage regulator from MPS (MP2019) that can handle 12V vehicle transient fluctuations and minimizes standby power consumption [12]. - An ON Semiconductor micro-stepping motor driver (NCV70517) is utilized for adaptive front lighting system (AFS) functionality, typically found in mid to high-end traditional fuel vehicles [13]. - A voltage follower from ROHM (BD42530) ensures dynamic voltage tracking for the light group, maintaining brightness control accuracy [14]. - The main LED driver system is powered by Texas Instruments chips, with a dual-channel constant voltage LED driver (TPS92682Q) and three synchronous buck LED drivers (TPS92520Q) for auxiliary lighting [14][15]. Conclusion on Component Selection - The analysis reveals that the Xiaomi SU7 headlight driver module employs a mix of high-performance international components and some local suppliers, indicating a strategy for supply chain diversification and reliability [16].

首先是毛利率与净利率双双下滑,好在降幅不大:一季度毛利率为37.44%,同比下降1.88个百分点;净利率12.56%,同比微降0.22个百分点。 作者:周源/华尔街见闻 兆易创新今年一季度业绩看上去很美,但应收账款和有息负债同比增幅较大,显示未来业绩增长可能承压。但供应链人士告诉华尔街见闻,这种可能性不 大,"兆易创新业务质地不错,就国内来说,属于第一梯队。" 2022-2023年,兆易创新业绩经历两年下滑态势:2022年利润下滑12.16%至20.53亿元,2023年净利润暴跌92.15%至区区1.61亿元。 这种惨相,在2024年得以扭转,并在2025年第一季度,继续了2024年的业绩景气度。但2024年盈利水平仅为2022年的53.72%,好在经营现金流和净现比指 标非常健康。 2024年和2025年一季度,兆易创新经营现金流分别为20.32亿元和3.36亿元(这个指标有点小问题,后文会提),均超同期净利润,净现比(经营现金流/净 利润)分别为1.84和1.43;在兆易创新利润最高的2021年,净现比仅0.97。 财报显示,兆易创新在今年Q1实现营业总收入19.09亿元,同比增长17.32%;归母净利润 ...
